一、前言在现代光度和辐射度计量中,常用的光辐射测量系统(简称为测光系统)是由光电探测器和光电信号处理及电测仪表组成的。对于大多数测光系统的一个基本要求是它的线性,也就是说它输出的电信号应与输入的光信号的强弱成正比。但是在实际工作中,我们使用的各种测光系统只是在一定范围内程度不同地接近于线性。所以在根据测量结果去计算光辐射量的量
I. Introduction In the modern photometric and radiometric measurement, commonly used optical radiation measurement system (referred to as the metering system) is composed of photodetectors and optical signal processing and electrical measuring instruments. A basic requirement for most metering systems is its linearity, which means that the electrical signal it outputs should be proportional to the intensity of the incoming optical signal. However, in practical work, we use a variety of metering system is only within a certain range of different degrees close to linear. So in accordance with the measurement results to calculate the amount of light radiation
