Airborne infection, facilitated by viruses present in particulate matter, emphasizes the importance of monitoring dust concentration as an indicator of virus spread. Our approach involves the implementation of a time-synchronized wireless sensor network for real-time sensing of dust concentration distribution. The time-synchronized wireless sensor network relies on a proposed time-synchronization algorithm, ensuring a time error of less than ± 1.27 ms. This precision enables the measurement of even fast-moving dust particles. To validate the feasibility of the wireless time-synchronized sensor network, we utilized a dust ejector (air cannon) and positioned time-synchronized sensors in a row. Dust particles released from the ejector passed through each time-synchronized sensor terminal. Simultaneously, a video recording (60 frames) was conducted, and the measured times of the time-synchronized sensor terminals were compared with the lap times of the video. The results of this comparison revealed identical lap times between the time-synchronized sensor data and the video, affirming the successful operation of the time-synchronized wireless distributed sensor node as designed.","PeriodicalId":722,"journal":{"name":"Optical Review","volume":null,"pages":null},"PeriodicalIF":1.2,"publicationDate":"2024-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142085065","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The optimal doping concentrations for the three dopant ions Nd3+, Yb3+, and Ho3+ were determined to be 1 mol%, 6 mol%, and 0.8 mol%, respectively, through the method of controlling variables. By analyzing the dependence of the up-conversion luminescence intensity on the pump current of the 980 nm laser, it was found that the green and red up-conversion emissions of Ho3+ ions under 980 nm laser excitation were both two-photon processes. Furthermore, the influence of temperature on the up-conversion luminescent properties of BaGeTeO6: Nd3+/Yb3+/Ho3+ green up-conversion phosphors under 980 nm laser excitation was investigated, and the temperature sensing properties of Ho3+ ions were discussed. The results indicated that, at room temperature and higher temperatures, both the red and green up-conversion emissions of the sample were two-photon processes. Within the range of excitation current used in the experiment, the ratio of red to green up-conversion luminescence intensity of Ho3+ ions was independent of the laser excitation current but correlated with the sample temperature. In the temperature range of 303–723 K, the ratio of red to green up-conversion luminescence intensity of Ho3+ ions exhibited a nonlinear relationship with temperature. Comparing the temperature sensing sensitivity of Ho3+ in different matrices, the results indicated that the sample possessed high temperature sensing sensitivity.","PeriodicalId":722,"journal":{"name":"Optical Review","volume":null,"pages":null},"PeriodicalIF":1.2,"publicationDate":"2024-08-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142042618","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The generation of the ultra-narrow transmission peak and the ultra-strong photonic localization in network is attributed to the mutation of states, which are significant improvements in the performance of all-optical switch. First, the ultra-strong photonic localization induces the Kerr effect in nonlinear material, which transforms the transmission peaks into a transmission valley and results in the super-high efficiency. The efficiency of switch based on CCOWN with 11 unit cell (UC) and each UC possessing 7 nodes was calculated and found to be approximately (1.38 times 10^{39}), which is 13 orders of magnitude better than previously reported. Furthermore, the ultra-strong photonic localization also leads to the ultralow threshold energy. Calculations reveal that the threshold control energy of all-optical switch based on CCOWN only with 7 UC and each UC possessing 5 nodes is about (5.78 times 10^{-30}) J, which is 5 orders of magnitude smaller than the best reported results. In addition, fitting formulas for the transmission and switching efficiency with UC number have been derived, and the results show that the switching efficiency increased exponentially with the UC number and nodes. This study not only presents a new model for designing all-optical switch with outstanding performance, but also provides the possibility for further practical use of all-optical switch, while deepening our insight into optical waveguide networks.","PeriodicalId":722,"journal":{"name":"Optical Review","volume":null,"pages":null},"PeriodicalIF":1.2,"publicationDate":"2024-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142002838","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

And the effects of Au nanoparticles on the light-absorption performance of thin films in the near-infrared wavelengths are investigated in terms of nanoparticle position, array period, and particle radius. And for the 1064 nm wavelength band, we obtain the optimal structural model. It has been shown that nanoparticle modification on the front side of the emission layer is the most effective in promoting light absorption; the resonance peaks formed by the surface plasmon excitations can greatly affect the light-absorption rate of Au nanoparticles adsorbed on the film, and the position of the absorption peaks can be changed by altering the array period and particle radius to achieve the enhancement of the film's absorption of light in a specific wavelength band. For the 1064 nm band, we obtain the best model, when the radius of Au NPs in the emission layer is 25 nm, and the model absorption with an array period of 150 nm is up to 84.85%, and the quantum efficiency is improved by one-third compared with the thin film.

Markers are crucial in the locator system, capturing the positions and orientations of surgical instruments and patients during operation. While spherical markers can be easily detected, they are less robust owing to limited feature points. In contrast, planar markers offer more feature points and greater resistance to occlusion. However, the demanding nature of orthopedic surgeries necessitates specific requirements for NIR-based planar markers, such as size, illumination, weight, and heat dissipation. To address these challenges, we designed an edge-lit NIR calibration board (300 mm × 300 mm) to calibrate the constructed NIR camera, with its effectiveness validated through extensive experimental studies. Based on the fundamental design data obtained from the designed edge-lit NIR calibration board, and considering the luminous flux density and the available 12 V battery on the market, we proposed an edge-lit active NIR planar marker with dimensions of 70 mm × 60 mm and equipped with eight LEDs (1.5 V, 0.085 W each). The experiential data illustrates the max relative standard deviation are around 0.93% and 0.78% for the measurement precision subjected to 10 mm × 10 mm square (5 × 5 squares) with 16 and 36 feature points, respectively. Further, we validated the following from the experimental results: (1) A 12 V 1000 mAh alkaline battery has an autonomy of approximately 16 h for the eight NIR LEDs. (2) The total heat energy conversion of 0.408 W for the marker is within acceptable limits for use in an operation room. (3) The total weight of approximately 21.6 g, including the planar marker and the selected battery, is manageable. Therefore, the designed edge-lit active NIR planar marker presents a viable option for integration into the locator system of orthopedic surgical robots.","PeriodicalId":722,"journal":{"name":"Optical Review","volume":null,"pages":null},"PeriodicalIF":1.2,"publicationDate":"2024-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141904437","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For the extensive use of PS in the imaging-lens systems, lower birefringence should be attained for the enhancement of the resolution. Previously, we have developed PS with extremely low birefringence (LB-PS) even when the molecular chain orientation of PS occurred. It indicates that PS may now become an effective material with excellent properties for optical lenses. In this paper, we compared the birefringence of our developed LB-PS with ones of commercial optical polymers that are most commonly utilized in imaging-lens systems. It was confirmed that the birefringence of LB-PS was comparable or even better than that of the commercial ones with high resolution. By designing an imaging-lens system, it was also confirmed that employing PS with the Abbe number of 31.5 could be highly effective in compensating for chromatic aberration as well as obtaining high optical resolution. Moreover, the resolution performance of several lens systems was calculated, analyzed, and compared by considering the birefringence of cyclo-olefin polymer (COP), normal PS, and LB-PS. It was found that LB-PS could maintain high resolution, while normal PS with high birefringence exhibited significant decrease in resolution. It was also found that LB-PS generated higher resolution than COP. All these results revealed that LB-PS could be an excellent optical material to compensate for the chromatic aberration of lens systems, leading to the enhancement of the actual resolution performance. It was, therefore, expected that LB-PS could contribute to improving the resolution performance of smartphone cameras and security cameras.","PeriodicalId":722,"journal":{"name":"Optical Review","volume":null,"pages":null},"PeriodicalIF":1.2,"publicationDate":"2024-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141891731","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A unique type of nanopillar formation has been observed on (textrm{SiO}_2) surfaces possessing antireflective properties when irradiated with a specific number of overlapping pulses, polarization, and fluence levels. Maintaining precise control over these sensitive technological parameters such as defocus and incident angle during the processing of geometrically complex shapes presents a significant challenge. This study proposes a theoretical optical arrangement to address this limitation by the design of a custom scanner system optimized for curved surfaces. The paper details the optimization process of such a bent image space (inverse-hypercentric) optical system using Zemax OpticStudio. Although the practical realization of the arrangement has not been performed, simulations are conducted to prove the functionality of the concept. Furthermore, we propose a practical method for segmented structuring of spherical surfaces based on consecutive repositioning and irradiation using an industrial robotic arm. By constructing the optical model, the necessary resolution of the segmentation has been calculated for a typical F-Theta scanner system and experimental verification has been performed.","PeriodicalId":722,"journal":{"name":"Optical Review","volume":null,"pages":null},"PeriodicalIF":1.2,"publicationDate":"2024-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141891728","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
