Incom has developed ALD-GCA-MCPs that use Atomic Layer Deposition (ALD) to coat Glass Capillary Arrays (GCAs) of a base glass in order to make MCPs. In this way, the electrical and mechanical properties of the MCPs are separated. One advantage of this is that Incom can make MCPs out of various types of glass, such as aluminosilicate, which is substantially free of alkalis that can migrate in the glass matrix and change the electrical properties of the MCPs. This process has enabled Incom, using their proprietary C14 glass, to make MCPs that have much longer device lifetimes. The goal of these experiments was to compare the lifetime performance of Incom MCPs to PbO MCPs, as well as to compare the performance of ALD-GCA-MCPs made out of two types of glass substrates: C14 glass and an alkali-containing C5 glass. The MCP made with C14 glass had a gain of 1E4 at 950 V after 300 C/cm2 extracted charge, and no spatial variations in gain out to at least 23 C/cm2. The MCPs made of C5 glass exhibited imaging defects after 3 C/cm2. The gain of the PbO MCP fell to 1E3 at 950 V after 110 C/cm2.","PeriodicalId":434863,"journal":{"name":"Optical Engineering + Applications","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117114104","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, traditional combiner-based HMDs are bulky, and thus limited their further application. To miniaturize the devices, diffractive waveguide devices are the best solutions. A relief grating is presented in this study. Through the Finite Element Method (FEM) rather than the traditional Rigorous Coupled-Wave Analysis (RCWA), the diffractive efficiency of relief gratings with different slant angles and different slit depths have been investigated with the wavelength around 532 nm and several incident angles. The relief grating had slits with a slant angle α, depth d, and periods a. In the FEM simulation environment, the grating was fabricated on the glass substrate surrounded by air, and the refractive indices are nglass = 1.5 and nair = 1. The diffractive efficiencies were analyzed in several slant angles with depths varying from 50 nm to 500 nm. The results showed that a deeper grating depth produced higher efficiency, and a larger incident angle resulted in stronger contributions to the corresponding diffraction order. The relief grating with different slant angles showed greater efficiency in the +1 order, while the efficiency of the −1 order decreased. The relief grating with a larger slant angle showed higher efficiency than the grating with a smaller slant angle. Overall, a larger slant angle effectively induced higher efficiency in the +1 order, and the depth can also give contributions to the diffractive efficiency enhancement.","PeriodicalId":434863,"journal":{"name":"Optical Engineering + Applications","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129708729","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}

This high-resolution camera is specifically designed to capture lunar surface images and facilitate the identification of potential landing sites for future missions. Leveraging the capabilities of the camera will significantly enhance our understanding of lunar geology, morphology, and evolution, laying a strong foundation for future lunar exploration. This paper introduces the configuration and features of the proposed LUTI camera, a highresolution electro-optical camera. It details the assembly and alignment process, presents performance measurement results, and elucidates its optical characteristics. Through precise alignment and calibration, this camera achieves a required swath width of > 8 km at an altitude of 100 km, providing a broader coverage of the lunar terrain. Its advanced components, including a sun shield and a Cassegrain-type telescope with hyperbolic mirrors, contribute significantly to its high-resolution imaging capabilities. Performance measurement results confirm that the LUTI camera meets the required specifications, including achieving a 10 % performance level for its modulation transfer function. The detailed imagery captured by the LUTI camera lays a strong foundation for future scientific research on the Moon, enabling researchers to conduct in-depth studies and investigations of lunar features and phenomena.","PeriodicalId":434863,"journal":{"name":"Optical Engineering + Applications","volume":"22 4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123504881","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}
