紫外光谱响应度测量系统设计

摘要

Because of the big errors in the ultraviolet radiation calibration measurement, this paper uses pyroelectric detector as the base probe to benchmark detector (GaN) for calibration, puts forward the design principles of spectral response measurement system and designs high stability Ultraviolet light source system, pyroelectric electrical calibration system, signal detection circuit, analysis the functions of computer control and software processing system. Finally , it uses monochromator wavelength calibration to prove that the accuracy of the system.%由于目前的紫外辐射的定标测量存在测量误差大的缺点,采用热释电探测器作为基准探测器给被测探测器(GaN)进行定标,给出光谱响应度测量系统的设计原理,对高稳定度紫外光源系统、热释电电学定标系统、信号检测电路进行了详细的设计,分析计算机控制和软件处理系统部分功能构成,最后进行了单色仪的波长标定来证明系统的准确性.
