The Gauss model of point target imageirradiance and the calculation model of the infrared radiation power are established.
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 results demonstrate that the irradiance on object, backscattering and signal irradiance on photo-cathode are increased and the image contrast between object and background is decreased.
