SPR spectroscopy is a label-free, non-destructive and highly sensitive measurement principle for detecting changes in the refractive index in close vicinity of a gold surface. A transfer of this technology to a miniaturized sensor will broaden the range of possible applications. Commercial SPR assays are mainly working with a small number of sensing spots. In contrast, the SPR imaging system shown here will allow the use of an array of many sensing spots. In combination with chemical receptors designed as an artificial nose or an electronic tongue, the simultaneous detection of many analytes is envisioned. So far, lasers or other inhomogeneous light sources were used to illuminate the sensing surface, which is decreasing the systems sensitivity. We show a compact (< 60 mm), low cost, LED based light source which is providing a large area (>300mm2) homogeneous top hat profile. The combination of a high bit-resolution camera with our new light source enables a reflectivity based surface plasmon resonance imaging system with a high refractive index unit (RIU) resolution.","PeriodicalId":294758,"journal":{"name":"International Conference on Photonics, Optics and Laser Technology","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114404088","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The numerical simulator is based on the coupled local mode theory (CLMT), which is a rigorous model that has the downside of requiring long computational times to compute the ICXT field and PDFs of the ICXT power. Conversely, a dual-polarization discrete changes model (DP-DCM) that allows for much faster estimates of the ICXT field is presented. It is shown that, for perfectly homogeneous MCFs, the mean ICXT power distribution between the polarization directions is similar, despite the power distribution at the MCF input, for a mean linear birefringence parameter ranging from 10−7 (low birefringence) to 10−4 (high birefringence), and for different MCF bending radii. It is also shown that the mean ICXT power estimates obtained with the CLMT and DP-DCM are very similar. Furthermore, using the CLMT, the PDFs of the ICXT power of the polarization directions are shown to be chi-squared distributions with two degrees of freedom, and the PDF of the sum of the ICXT power of the polarizations is shown to follow a chi-squared distribution with four degrees of freedom.","PeriodicalId":294758,"journal":{"name":"International Conference on Photonics, Optics and Laser Technology","volume":"139 18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127058869","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to investigate the ingredient variation and aging effects of the optical film caused by i-line light, a UV light irradiation environment was built with an optical power of 80 mW. In the experiment, the reflective and anti-reflective film was coated on the BK-7 glass and irradiated by 24 to 120 hours. Then, the reflectivity/transmittance and the ingredient of optical film was measured and analyzed. The reflectivity and transmittance of optical film varied after 24 hour irradiation and decreased approximately 1.67 and 0.9 wt% after 120 hours irradiation, respectively. In addition, the results obtained from the focused ion beam (FIB) system indicated that the ingredient of oxygen of both films increased and the anti-reflective film ruptured evidently under 120 hours of irradiation.

The optimized micro-mirror actuating structure consists of three individual levers, each of which is actuated by electrostatic attractive force with the plane-parallel structure to produce a large upward displacement at the end of the long arm of the lever with the lever principle. Finite element analysis (FEA) models are built to calculate the maximum upward displacement of the long arm. The actuator with 320 um long arm and 80 um short arm were designed by 2um thick Poly1 layer, while the electrodes were designed by Poly0 and mirror plate was designed by Poly2 with a polish process afterwards. The micro-mirrors can be tightly arranged in a hexagonal array to be applied in adaptive optics (AO) system as a deformable mirror. An AO simulation system is built to test the aberration correction effect of the micromirror array. The results showed that the 61 micro-mirror array is better than 37 micro-mirror array in aberration correction, which showed good application prospect of this high stoke micro-mirror array in AO systems.","PeriodicalId":294758,"journal":{"name":"International Conference on Photonics, Optics and Laser Technology","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125577881","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
