An equivalent focal plane assembling module is designed to avoid frequent installation of expensive CCD during measurements.The equivalent module is precisely manufactured according to measured dimensions of CCD module. It also provides simulated spectral image that could be observed by microscope. By measuring distance between real and simulated spectral image,spacer's reshape value is calculated,and spectral image is aligned to CCD laterally. Experiment shows that the whole spectral image's defocusing value is in focal depth in the presence of tool microscope measuring error,spacer reparation error and interchangeability error. MTF is higher than 0. 3after 3 iterations in experiment,which shows an improvement on efficiency and safety.","PeriodicalId":10133,"journal":{"name":"Chinese Journal of Optics and Applied Optics","volume":"32 1","pages":"644-650"},"PeriodicalIF":0.0,"publicationDate":"2014-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74288389","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}

According to the current value of dynamically tuned gyro output at different latitude we designed a system which can automatically adjust the sample resistor value using digital potentiometer. The data processing system calculates the latitude automatically based on dynamically tuned gyro signal and then the signal acquisition system resets the acquisition resistor value,and thus we can acquire the sin wave curve efficiently. Using this method we ensure that the north finder can meet the accuracy requirements at different geographical latitudes,and has strong adaptability and high stability.","PeriodicalId":10133,"journal":{"name":"Chinese Journal of Optics and Applied Optics","volume":"14 1","pages":"786-793"},"PeriodicalIF":0.0,"publicationDate":"2014-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84732347","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}

Two beams with wavelengths of 532 nm and 515 nm are combined into one in the combination and detection system using light filter with special optical thin films,and the combination accuracy is detected. Based on this system,the corresponding theoretical model is established,and the comprehensive analysis on the error source and the value in combination and detection are given in this paper. When the pointing stability of both beams is 50 μrad,the theoretical value of combination accuracy is 14. 69″,and the proportion of pointing stability is99. 26%. The system gets an excellent anti interference ability against the unstable factor such as the error of centroid location( error rate 3 times),and the variation in accuracy rate is less than 2. 4 ‰. When the laser pointing stability is increased to 23. 51 μrad,the highest theoretical value of combination accuracy is 7. 09″and the proportion of pointing stability is 96. 77%. The system still has a high ability of anti-interference and the variation in the accuracy rate is less than 1%. Factors that affect the beam combination accuracy of near field and small power are laser beam pointing stability,mechanical adjustment and centroid location error are all the factors to affect the combination accuracy of the near field beam with low power,among which the laser pointing stability is the main factor. Adjusting the proportion of each factor,we can control the ability of anti interference of beam combination.","PeriodicalId":10133,"journal":{"name":"Chinese Journal of Optics and Applied Optics","volume":"31 1","pages":"801-807"},"PeriodicalIF":0.0,"publicationDate":"2014-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90917712","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}

The nonuniformity of thermal imager is corrected using surface blackbody under different temperatures. The relationship between the gray and blackbody radiance is obtained by thermometry experiment of blackbody target. The mathematical calculation model of target temperature is established and the error of thermometry result is analyzed. The results show that the drift of gray of thermal image as nonuniformity correction radiance under different correction temperatures can be treated linearly,and is independent on the target temperature. When the nonuniformity is low,the temperature measurement error of the thermal imager is less than 0. 22 ℃,which greatly reduces the temperature measurement error of the cooled medium-wave infrared thermal imager after nonuniformity correction under different correction temperatures.","PeriodicalId":10133,"journal":{"name":"Chinese Journal of Optics and Applied Optics","volume":"40 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2014-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72781475","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}
