紫外光阴极辐射灵敏度的测量误差
Measurement errors of ultraviolet photocathode radiant sensitivity
摘要
Abstract
Photocathode radiant sensitivity is an important index to measure response capability of ultraviolet detector,thus its accurate measurement is necessary.Herein,measurement methods of photocathode radiant sensitivity for some type of ultraviolet detector were built,and practical measuring equipment of ultraviolet photocathode radiant sensitivity was constructed.Influencing factors for the measurement of ultraviolet photocathode radiant sensitivity by the equipment were analyzed emphatically.In addition,errors in the measurement of photocathode radiant sensitivity with combinations of UV narrow band filter,optical grating monochromator respectively with radiant illuminometer and radiant power meter were compared,obtaining that the error for measuring photocathode radiant sensitivity by the combination of combined optical grating monochromator with radiant illuminometer was minimum.The expand uncertainty was 9%,which had absolute advantages than other three combinations with expand uncertainties of 19.4%,19% and 11.2%.The research achievement can support the research and development of domestic ultraviolet detectors,thus providing an effective and accurate detection method for improving and promoting the technical performance of ultraviolet detectors.关键词
