摘　　要：基于辐射度学理论搭建了用于激光诱导击穿光谱探测系统的绝对效率标定装置.用卤钨灯配备紫外玻璃滤光片和熔融石英漫射片作为标定的标准光源,标定了配备Czerny-Turner型紫外波段光谱仪的激光诱导等离子体光谱探测系统.测得了系统在310~385nm波长范围内的绝对光谱响应,不确定度小于7%(在标准偏差为2的条件下).绝对效率标定可为激光诱导击穿光谱探测系统硬件评估提供一种手段.An absolute calibration setup for laser-induced breakdown spectroscopy detection system is built based on the radiometry theory. A tungsten halogen lamp equipped with an ultraviolet glass filter and a fused silica diffuser is used as standard light source for the calibration. Absolute calibration of a laser-induced breakdown spectroscopy detection system with a Czerny-Turner spectrometer in the ultraviolet range is performed. The absolute spectral response of the system in the range of 310~385 nm is obtained with an uncertainty less than 7% by 2 standard deviation estimate. The absolute spectral calibration provides a way to evaluate the hardware of the laser-induced breakdown spectroscopy detection system.
