However, after the synthetic aperture telescope is deployed in orbit, there will remain tilt and piston error between adjacent segments, which will sharply deteriorate the imaging quality of the optical system. The traditional piston error detection method based on dispersed fringe sensor has the question that it is difficult to detect the piston error within one wavelength, and the detection accuracy is restricted by the detection range. The method in this paper constructs multiple monochromatic light channels by opening windows in different areas on the dispersed fringe pattern, calculating and obtaining the feature value in each window to form a feature vector. Then, the convolutional neural network is introduced to distinguish the feature vector to detect piston error. Among them, the training set construction method adopted in this paper only needs raw data in one wavelength to construct a training set covering the entire detection range. Through simulation, the method proposed in this paper achieves the detection range of [-208λ, 208λ] (λ=720nm), and regardless of the presence of noise, the root mean square value of the detection error does not exceed 17.7nm (0.027λmin, λmin=660nm).","PeriodicalId":236529,"journal":{"name":"International Symposium on Advanced Optical Manufacturing and Testing Technologies (AOMATT)","volume":"55 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":"114276951","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, it is rarely reported about the effect of surface recombination on tandem solar cells. In this paper, we analyze the influence of surface recombination on the performance of tandem cells. Simulations show surface recombination can reduce the cell’s open-circuit voltage (Voc), short-circuit current (Jsc), and efficiency. The efficiency of the tandem cell decreases with the increase of the surface recombination rate on the sub cells. The maximum efficiency of the tandem cell without surface recombination is 25.81%. When the recombination velocity of the silicon sub cell increases from 0 to 105 cm/s, the overall efficiency decreases to 13.96%. When the same surface recombination velocity is added to perovskite sub cell, the overall efficiency is 13.89%. When both the surface recombination velocity of perovskite and silicon are 105 cm/s, the efficiency of the tandem cell decreases to 13.42%. Therefore, the performances of the tandem cell are similar in the cases of single sub cell with surface recombination and both sub cells with surface recombination.","PeriodicalId":236529,"journal":{"name":"International Symposium on Advanced Optical Manufacturing and Testing Technologies (AOMATT)","volume":"9 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":"122182315","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, due to the higher hardness and lower fracture toughness of this material, brittle fracture is very prone to occur during single-point diamond machining, resulting in poor surface finish and roughness. Hence, like ceramics, and composites, the machining of this alloy is considered as difficult-to-machining materials. Micro-laser-assisted machining (μ-LAM) method has become a promising solution in recent years to lessen cutting stress when materials that are considered difficult-to-machining, such as sc-Si and ZnSe are employed. This paper investigated the influence of input variables of μ-LAM on the machinability aspect of the sc-Si. The influence of cutting parameters on surface roughness in LAM is studied by orthogonal experiment, and optimal processing conditions are obtained. The second-order regression model of process parameters and surface roughness was established by response surface method. The results show that the change of cutting depth had little effect on surface roughness, the spindle speed and feed speed were main factors affecting the surface roughness. According to the 3D response surface, the interaction between different factors had a significant effect on surface roughness. The optimal combination of process conditions were a spindle speed of 4000rpm, a feed speed of 2mm/min and a cutting depth of 5μm.","PeriodicalId":236529,"journal":{"name":"International Symposium on Advanced Optical Manufacturing and Testing Technologies (AOMATT)","volume":"108 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":"128282900","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}

After moving, vibration or change of ambient temperature, the collimator components location will change, and its own parallelism will disorder. Outside the laboratory, it's difficult to recalibrate the disorder collimator. This will directly affect the reliability of the collimator measurement results. In this paper, a self-calibration method was proposed, the collimator structure was optimized, CCD detection imaging was introduced and self-calibration component was designed. The radial calibration and depth of focus calibration principles were studied in collimator. Based on this, a set of collimator will be developed, which can measure the optical axis parallelism and its own parallelism included. When the collimator own parallelism disorders in the use of an external field, it's easier to finish the self-calibration in the scene. The measurement accuracy of the instrument can be ensured. A set of sun fleck positioning system software will be programmed, and it can be used to coordinate with self-calibration and measuring the optical axis parallelism function in the collimator. The study in this paper has important practical significance for scientific research and engineering experiments.","PeriodicalId":236529,"journal":{"name":"International Symposium on Advanced Optical Manufacturing and Testing Technologies (AOMATT)","volume":"1 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":"130650190","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}

Because of its high sensitivity, high resolution, and non-destructive testing, it is widely used in various fields. In this paper, OCT is used to detect and evaluate the reproduction of the three bacteria. At the same time, we also use a 20-fold objective lens to observe the morphology of the three bacteria at the position of the sample arm of the OCT. In the experiment, three groups of experimental data were collected, which were pictures collected after two hours, four hours, and five hours of bacterial culture. From the experimental data, the morphology and colony reproduction changes of the three bacteria can be observed; after 4 hours of reproduction, the morphology of E. coli and aeruginosa can be observed; Morphological structure of the three bacteria could be observed after 5 hours of reproduction; through the three-dimensional reconstruction of the experimental data, the three-dimensional morphology of the bacteria can be seen more clearly, which is more conducive to the identification of bacterial species. Experimental results show that OCT can be used to detect bacterial organisms on the order of micrometers, and can observe the reproduction process and morphology of bacteria in different periods, to identify bacterial species. This is of great help in the non-invasive identification of bacterial types in clinical applications of biomedicine.","PeriodicalId":236529,"journal":{"name":"International Symposium on Advanced Optical Manufacturing and Testing Technologies (AOMATT)","volume":"93 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":"134525051","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}
