This ultrathin camera features inverted microlens arrays (MLAs), light blocking layers composed of metal and black photoresist, spacers and an image sensor. The imaging results through the camera with the light blocking structure showed that the MTF 50 was enhanced about twice and the Michelson contrast increased about 4 times than the value without the layers. Imaging for counterfeit bill discrimination was successfully performed using the ultrathin digital camera. This ultrathin camera can offer a new opportunity in the field of surveillance, and biomedical imaging.","PeriodicalId":353010,"journal":{"name":"2019 International Conference on Optical MEMS and Nanophotonics (OMN)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130616437","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}

We present the development of free-form tunable MEMS mirrors to generate non-diffracting beams with unique spatial profiles.

The actuation is achieved by thermal expansion of a polymer layer, which defines the final tuned shape of the mirror. The deflection of the mirror surface and the resulting iry beam is characterized.","PeriodicalId":353010,"journal":{"name":"2019 International Conference on Optical MEMS and Nanophotonics (OMN)","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123065197","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}

However, conventional colorimetric-based sensors have shown shortcomings in terms of response time, sensitivity and selectivity. To overcome the difficulties, this study proposes a novel method for highly sensitive photonic crystal (PC) based VOC sensor by increasing the intimal distance between nanoparticles. Silicon liquid is used to change the initial interdistance by chemical swelling, and it is fixed by replacing the swollen space with premixed PDMS. As a result, more color change (handgap shift) occurs as the initial interparticle distance increases, and the performance improved up to 24.0 %.","PeriodicalId":353010,"journal":{"name":"2019 International Conference on Optical MEMS and Nanophotonics (OMN)","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130738196","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}
