Pixel binnng is proposed to compensate the time of exposure and to improve the brightness and contrast as well as SNR of the images. And a region selection algorithm is used to select the image region by which we can estimate the displacement using gray projection algorithm. The experiment results show that the error is 1 pixel by utilizing the improved algorithm,which greatly enhance the accuracy and stability.","PeriodicalId":10133,"journal":{"name":"Chinese Journal of Optics and Applied Optics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76547183","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}

We discussed the physical meaning of the RCR combined with the observation instances of the 1. 23 adaptive optical telescope. The range of the application of the RCR,the error influence factors and the effect of the atmospheric dispersion on the RCR were also analyzed. The result shows that the RCR could completely reflect the correction effectiveness of the adaptive optical telescope and the physical meaning of the RCR wasintuitive. RCR can be applied to the estimation of the correction effectiveness of a telescope that can get the characterization of the wavefront. The error of the RCR mainly depend on the measurement error of the wavefront sensor. The effect of atmospheric dispersion on the RCR can be neglected.","PeriodicalId":10133,"journal":{"name":"Chinese Journal of Optics and Applied Optics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78769602","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 addition,an optical passive compensation method is used to realize an athermalized design in the range of- 40 ~ + 50 ℃ by choosing proper optical and structural materials. The design results show that the optical system's modulation transfer function in each field is close to the diffraction limit at different temperatures under the characteristic frequency of 20 lp /mm and the system size is compact with fast FOV switching.
