In hollow face illusion, the direction of the 3D face changes according to the observation angle although the 3D face itself is static. Arc 3D display can show simple 3D image that is visible over a wide viewing angle by use of a thin substrate and illumination light. This structure is suitable for various applications such as digital signage or entertainments with illusion. If rotational perception like hollow face illusion would be obtained by simple aerial images like simple illustrations, application zone could be expanded to various field, such as animation or marks. To investigate the addition of rotation perception in 3D image with arc 3D display, we study perceived rotation angle of face-like illustration with inverted concave depth. In this paper, we quantitatively investigate the perceived rotation angle of the face image due to changing observation position and perceived depth position of face-like parts. The perceived rotation of the face image illustration can be achieved although the perceived depth of the face-like parts has various values by subject.","PeriodicalId":722,"journal":{"name":"Optical Review","volume":"18 1","pages":""},"PeriodicalIF":1.2,"publicationDate":"2025-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143392956","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 broadband polarization filter and a temperature sensor can be achieved based on the same simple PCF structure, with a hollow core separately filled with liquid crystal and toluene. The polarization filtering and sensing properties of the proposed PCF were studied using the finite element method (FEM). Numerically results show that variations in the diameter of both the liquid crystal-infiltrated central hole and the cladding air holes have a slight effect on the polarization filter characteristics. The polarization filter can be effectively tuned in terms of the central wavelength, crosstalk, and bandwidth by adjusting the thickness of the gold film. The proposed PCF polarization filter with t = 22.5 nm has achieved a wide bandwidth of 1850 nm across wavelengths ranging from 1.2 to 3.05 μm for a fiber length of 50 μm, achieving a high value of polarization loss ratio (PLR) of 28,717 at λ = 1.31 μm with losses of 1723 dB/cm for y-polarization and 0.06 dB/cm for x-polarization. The y-polarized core mode in this design with t = 10 nm is rapidly attenuated, experiencing losses larger than 1340 dB/cm over wavelengths ranging from 1.9 to 3.0 μm; it also exhibits a bandwidth of 2200 nm with crosstalk greater than 20 dB when using a fiber length of 50 μm at wavelengths above 1.5 μm. Furthermore, a temperature sensor that utilizes toluene as its core material exhibits a consistent average sensitivity of 6.68 nm/°C for y-polarization and can detect temperatures ranging from − 10 to 40 °C. The sensor maintains stable sensitivity within ± 1% fluctuation of the gold film thickness in the sensing range of − 10 to 40 °C.","PeriodicalId":722,"journal":{"name":"Optical Review","volume":"62 1","pages":""},"PeriodicalIF":1.2,"publicationDate":"2025-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143375148","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}

This paper presents a novel mid-air imaging optical plate, termed the truncated cylindrical array plate (TCAP). TCAP is composed of transparent cylinders with obliquely truncated ends and mirrors, specifically designed to address issues such as stray light and limited viewing angles in existing mid-air imaging optical elements. We evaluated TCAP through computer simulations and by fabricating a prototype optical element. Ray tracing simulations and stereo matching algorithms demonstrated that mid-air images are symmetrically formed on the side opposite of the light source relative to the TCAP. Furthermore, the simulations indicated that a bright, stray-light-free mid-air image could be achieved within a horizontal viewing angle of approximately (pm , 40 ^circ ). Experimental evaluation using a handcrafted prototype further confirmed the plane symmetry of mid-air image formation, validating its functionality as a mid-air imaging element. The proposed method is advantageous in systems where stray light is problematic, such as mid-air image interaction systems or optical systems utilizing mid-air imaging elements.","PeriodicalId":722,"journal":{"name":"Optical Review","volume":"9 1","pages":""},"PeriodicalIF":1.2,"publicationDate":"2025-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143192364","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}

Conventional techniques, including off-axis computer-generated holograms (CGH), double-phase holograms (DPH), and kinoforms, often encounter issues like low diffraction efficiency, limited spatial resolution, and high speckle noise. Although the dual-phase modulation method (DPMM), which employs two spatial light modulators (SLMs), achieves high diffraction efficiency, its spatial resolution is constrained by the intrinsic pixel size and resolution of the SLM. To overcome this limitation, we propose the PS-DPMM, an extension of the DPMM that introduces a 1/2-pixel shift between two SLMs. Although this sacrifices a portion of the modulation performance, it effectively improves the spatial resolution of complex amplitude modulation by nearly doubling. Through numerical simulations and experimental validation, we demonstrate that the PS-DPMM attains almost twice the spatial resolution of conventional methods while maintaining a relatively high-quality modulation. This approach provides a promising solution for advancing high-spatial-resolution SLM-based complex amplitude modulation with potential applications in holographic displays, fiber-optic systems, and other fields requiring high spatial resolution wavefront control.","PeriodicalId":722,"journal":{"name":"Optical Review","volume":"25 1","pages":""},"PeriodicalIF":1.2,"publicationDate":"2025-02-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143077580","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 investigation uses the finite element method and the simulation results show that the x-polarized fundamental mode (XPFM) is well confined within the fiber core, while the lowest-loss higher-order mode (LL-HOM) exhibits significant loss, and y-polarized fundamental mode (YPFM) exhibits even greater loss. Specifically, the loss difference between the XPFM and the LL-HOM is 15.39 dB/cm at 1 THz. After a 2 cm transmission length, the LL-HOM achieves an extinction ratio of 30 dB, while the insertion loss of the XPFM is only 0.67 dB. Furthermore, when the length of the filter is fixed at 4.1 cm, stable single-mode transmission of the XPFM is maintained over the frequency range from 0.755 THz to 1.075 THz, with the insertion loss of the XPFM remaining below 1.5 dB. The proposed filter demonstrates excellent fabrication tolerance and holds significant potential for applications in terahertz systems.","PeriodicalId":722,"journal":{"name":"Optical Review","volume":"47 1","pages":""},"PeriodicalIF":1.2,"publicationDate":"2025-01-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142975032","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}
