基于红外激光积分球的硅探测器响应非线性研究
Research on Nonlinear Response of Silicon Detectors Based onlnfrared Laser Integrating Sphere
摘要
Abstract
0.9 µm is one of the main working bands of the high temperature standard photoelectric and radiation thermodynamic temperature measurement in our country,so it is xery important to study the nonlinearity of the filter radiometer in this band.A nonlinear measurement system for spectral response of silicon detector was designed and built based on the flux multiplication method of single-phase dry light source double optical path.The flux was regulated by double-violet external fused quartz spectroscope,and the detector field of view was completely filled by integrating sphere to improve the repeatability of incident light in the photosensitive area of the detector.The high absorption light trap was used to avoid multiple reflections during flux regulation.The experiment extends the photocurrent range by switching the neutral density filter,and characterizes the nonlinearity of the 0.9 µm filter radiometer in the photocurrent range 1.6 × 10-8～8 × 10-6 A.The nonlinear value of single measurement is-8.7 × 10-5～4.8 × 10-5,the standard uncertainty of single measurement is better than 3.7 × 10-4,the nonlinear value of cumulative measurement is-2.7 × 10-4,and the standard uncertainty is better than 7.6 × 10-4.关键词
