CCD imaging luminance meter of wider range measure is obtained by using CCD with the function of charge cumulation, using methods of charge and digital cumulation.
In another technique, the light source layer's point spread function is decomposed into a plurality of components, and an effective luminance pattern is determined for each component.
在另一种技术中，将光源层的点扩展函数分解成多个分量，并对每个分量确定一个有效亮度模式。

Based on the Planck principle, it is deduced that the BIIR output voltage is the product of a constant and a monotonic increasing function of radiation luminance from the extended sources.
