本文叙述了一种利用高稳定光源和微机技术校准光电倍增管灵敏度的新方法.实测表明,其灵敏度稳定性可长期控制在1％以内。此系统已成功地应用于CL—1型彩色亮度计中。
In this paper, a new method to calibrate the sensitivity of photomultiplier tube using high-stability light source and microcomputer is described. The measured results show that its sensitivity and stability can be controlled within 1% for a long time. This system has been successfully applied to the CL-1 color luminance meter.
