光度计是专门用于测量发射,反射或透射光的光通量,亮度,照度或发光强度等。
Photometers are specifically designed to measure emitted, reflected or transmitted light in photometric terms of luminous flux, luminance, illuminance or luminous intensity.
因此建立一个高精度的光谱辐照度和光谱辐亮度标准是非常必要的。
The Gauss model of point target image irradiance and the calculation model of the infrared radiation power are established.
