Based on the polarization Twyman-Green interferometer, the experimental device of surface detection is built. By analyzing the problems in the experimental process, the following improvements are made on the original basis: firstly, when using the dual optical path system to collect fringes, it is found that the interference of air has a great impact on the image quality, so we refer to the principle of Fizeau interference, In order to improve the anti-interference ability of the whole system, the double optical path structure of the Twyman-Green interferometer is combined into a common optical path structure. Secondly, because the detection aperture and surface type will be greatly limited by the standard mirror, so based on the previous research of the research group, this design designs a large F number and long focal length standard mirror for the detection of different lenses, especially the convex mirror. Finally, in order to improve the contrast of interference fringes, a plane mirror film with suitable transmittance and reflectance ratio is designed by using optical coating software to improve the contrast of interference fringes.","PeriodicalId":236529,"journal":{"name":"International Symposium on Advanced Optical Manufacturing and Testing Technologies (AOMATT)","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124234599","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 this trend, optical phase change materials (OPCMs) based active devices emerge as promising solutions due to advantages of large optical contrast between the amorphous and crystalline states, optically or electrically switchable and non-volatile control, easy to integration etc. In this paper, we propose a non-volatile O-PCMs photonic switch by integrating a thin film of germanium antimony telluride (GST) alloy on top of a micro-ring resonator. As confirmed by our analytical and computational results, upon an amorphous-to-crystalline phase change, two output ports of the O-PCM microring switch exhibit gigantic transmission contrast with a ratio up to highest 47:1. Further, the O-PCM based photonic switch also demonstrates extremely low extinction ration to 13.58 dB and 14.40 dB for both output ports from 1.5 μm to 1.6 μm.","PeriodicalId":236529,"journal":{"name":"International Symposium on Advanced Optical Manufacturing and Testing Technologies (AOMATT)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127837146","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 view of a cylindrical surface sub-aperture stitching algorithm based on discrete phase data, by using Legendre polynomials to fit the wave surface, numerical simulation and analysis for several main influencing factors have been carried out. For instance, a bicubic interpolation method has been used for non-numerical point in a discrete phase and fuzzy points in overlapping areas during the process of stitching sub-apertures, on account of its accuracy and calculation time. By considering alignment error, random noise, position error, especially rotation error in non-rotationally symmetrical cylindrical surface testing, we stimulate 9 sub-aperture phase data from a measured phase data to analyze the correction coefficient which determines the percentage of error correction in stitching algorithm. While the correction coefficient is approaching 1, the stitching result is most likely overcorrected. In order to achieve the best error correction, the correction coefficient should be set at around 0.6. Furthermore, combined with chaos particle swarm optimization, we reduce the possibility of the algorithm falling into the local optimum, and improve the accuracy of stitching.","PeriodicalId":236529,"journal":{"name":"International Symposium on Advanced Optical Manufacturing and Testing Technologies (AOMATT)","volume":"406 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115586865","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 this study, a novel organic-inorganic hybrid material of tin oxide (SnO2) nanoparticles (NPs) and perylene diimide derivative (PDINO) is introduced as the electron transport layer (ETL) to improve both the device performance and the device stability of non-fullerene OSCs. Compared with the pristine SnO2 NP ETL-based device, not only the PCE of the PM6:IT-4F OSC with SnO2:PDINO as ETL is efficiently improved from 11.3 % to 12.7 %, but the shelf life of the SnO2:PDINO ETL based device is also extended. After being stored in ambient condition without encapsulation for 360 h, the PCE of the modified ETL-based OSC still retains 80 % of its original value. The incorporation of PDINO dopant can provide more favorable interfacial properties between the ETL and the active layer as well as reduced surface defects of SnO2 NP ETL, thus contributing to charge transport efficiency, suppressing molecular recombination, and protecting the active layer from degradation.","PeriodicalId":236529,"journal":{"name":"International Symposium on Advanced Optical Manufacturing and Testing Technologies (AOMATT)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115101470","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}
