By means of dissipative and dispersive coupling mechanisms, the changes of the relative position between the SNAP resonator and fiber taper not only bring the shift in a resonant wavelength, but also lead to the variation of the linewidth and extinction ratio of the whispering gallery mode (WGM) in spectrum. Instead of the wavelength shift, we utilize the extinction ratio changes to realize the displacement sensing, which is robust against lasing and microresonator frequency noise in the detecting system. Using the analytical expression of the transmission spectrum, the extinction ratio as a function of the displacement for different axial modes is obtained. It is proved that a large range and high resolution displacement sensor can be achieved by simultaneously tracking the extinction ratio of multiple axial modes. The fiber-based SNAP resonator can be fabricated into a probe-type sensor, making it potential and a powerful tool for many displacement sensing applications such as microstructure measurements in both aerospace and nano-lithography fields.","PeriodicalId":236529,"journal":{"name":"International Symposium on Advanced Optical Manufacturing and Testing Technologies (AOMATT)","volume":"8 Suppl 2 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":"126139854","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}

They have the characteristics of high accuracy, poor rigidity, and easy deformation. The uncertainty of their deformation has an important impact on the overall performance and subsequent use of the equipment. Weak-rigid plates are one of the most common types of weak-rigid components. At present, the research on weak-rigid plates mainly focuses on the deformation control of the workpiece during processing, and there are relatively few studies on the measurement of comprehensive parameters. The surface profile parameters of the weak-rigid plate will reflect the performance and processing quality of the weak-rigid plate. In this paper, a comprehensive index measuring device for weak-rigid components based on dispersion confocal sensor and a stress change test system for weak-rigid components based on dynamic interferometer are used to accurately measure the surface profile of weak-rigid plates, which provides a basis for its process parameters and subsequent assembly use. It provides a reference for the subsequent measurement of the surface profile and thickness of weak-rigid curved components.","PeriodicalId":236529,"journal":{"name":"International Symposium on Advanced Optical Manufacturing and Testing Technologies (AOMATT)","volume":"43 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":"122315580","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}

Due to the influence of machine motion error, clamping error, tracking error and other factors, ultra-precision turning often deviates from the ideal position during the actual machining process. Various error factors are coupled with each other, and it is difficult to compensate by establishing an accurate error model at present. This paper proposes an optical surface error compensation method based on zernike polynomials. Firstly, the surface error is reconstructed with Zernike polynomials. Then, by analyzing the frequency distribution of the optical surface error, the error corresponding to a specific Zenick coefficient is selected. Finally, based on the fast tool servo system, the original machining path is corrected according to the error compensation strategy. By compensating a Φ100 mm mirror, the surface accuracy is improved from PV 1.83 μm, RMS 0.47 μm to PV 0.38 μm, RMS 0.04 μm. The experimental results show that the error compensation strategy proposed in this paper can significantly reduce the optical surface error and improve the machining accuracy.","PeriodicalId":236529,"journal":{"name":"International Symposium on Advanced Optical Manufacturing and Testing Technologies (AOMATT)","volume":"12071 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":"129146120","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, as a highly coherent light source, laser speckle will be generated by the interference phenomenon of the reflected light or transmitted light of different surface elements after the incident on the surface of the object, which will seriously reduce the quality of the display image. Therefore, the suppression of laser speckle and the reduction of speckle contrast are always important problems in laser display technology. Here, we presented a speckle suppression scheme suitable for projector optical systems. Speckle suppression by spectral broadening and speckle suppression by superposition of multiple independent and unrelated speckle patterns are included in the scheme. Then, the feasibility of the scheme was verified by simulation. On this basis, the projector system was built. The speckle suppression scheme was added, and the effect of the scheme on speckle contrast was verified by actual measurement, and the speckle contrast was successfully reduced from 0.129 to 0.041, which was difficult for human eyes to distinguish.","PeriodicalId":236529,"journal":{"name":"International Symposium on Advanced Optical Manufacturing and Testing Technologies (AOMATT)","volume":"12074 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":"129442870","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, high precision aspherical optics are not widely used in many fields due to the high cost of manufacturing. In order to reduce the cost, an approach to realize the fast manufacturing of high precision aspherical optics is proposed. The bonnet polishing, computer controlled optical surfacing (CCOS) and magnetorheological finishing (MRF) are utilized in combination during the manufacturing process. Firstly, the rough polishing of the aspherical optics is accomplished by bonnet polishing. Secondly, the surface error are smoothed to reduce mid-frequency surface error by CCOS smoothing polishing equipment. Finally, the deterministic manufacturing is carried out by MRF equipment. The fast manufacturing technology has been applied on a paraboloidal mirror of 237mm in diameter. The experimental results show that aspherical optics can reach λ /60 (rms, @λ =632.8nm) in 33 hours by using the combined manufacturing technology. The fast manufacturing technology can provide high precision and high efficiency for aspherical optics.","PeriodicalId":236529,"journal":{"name":"International Symposium on Advanced Optical Manufacturing and Testing Technologies (AOMATT)","volume":"17 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":"131068900","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}
