The different imaging characteristics would enable the imaging system to achieve a variety of functionalities. In our approach, we designed and demonstrated a miniaturized six-channel multiresolution imaging system which allows a relative magnification ratio of up to 10 times between the different channels. The imaging system consists of two double-sided lens arrays replicated in-house in a polymer material through hot embossing. The mold inserts of the lens arrays were made in brass through ultra-precision diamond tooling. The replicated lens arrays were assembled together with a baffle block aiming at reducing crosstalk between neighboring channels. The assembled system was then integrated with a Sony full-frame image sensor and tested in proof-of-concept experiment. The acquired images using the integrated imaging system met the expectations compared to the simulation. This opens up new possibilities and functionalities in a compact imaging system.","PeriodicalId":386109,"journal":{"name":"International Optical Design Conference","volume":"105 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117184649","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 transition from ray tracing taking minutes to taking fractions of a second has changed the way lens design is taught and approached. Today's powerful computational tools have largely supplanted fundamentals, yet the synergy of thoughtfully combining theory with numerical capacity is what leads to the greatest insight, most efficiently. Recently uncovered materials of Professor Kingslake's highlight this fact and suggest how lens design's past has enduring importance today.","PeriodicalId":386109,"journal":{"name":"International Optical Design Conference","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132507466","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 system was originally developed for applications in two-photon microscopy (TPM). The optics provide for a perfect scanning spot along an arcuate line with no off-axis aberrations. On-axis aberrations are corrected with a free-form compensator placed on the input beam. The perpendicular scanning dimension to the scan line is obtained by linearly translating the whole microscope with respect to the specimen or moving the specimen. The design examples presented are for a 30-mm scan line and an NA of 0.5, and are both refractive and all-reflective, thus with minimum dispersion to prevent pulse broadening.","PeriodicalId":386109,"journal":{"name":"International Optical Design Conference","volume":"07 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128946340","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}

Sur- face geometric and real raytrace methods are compared for evaluation of homogeneous freeform surface PALs. Raytrace evaluation is compared with evaluation results from commercial lens design software for single vision lenses. A GRIN PAL base design is evaluated using the real raytrace method, and characteristic PAL behavior is demonstrated.
