Abstract
The present invitation relates to an optical radiation measurement method based on light filter units, comprising the steps of: 1) providing characteristic filter units and correction light filter units in front of detection units to obtain multiple measured response values of an object to be detected; and, 2) selecting one or more sampling regions within a waveband to be detected, and calculating, according to a corresponding simultaneous expression/equation system of the measured response values, a spectral power distribution within the waveband to be detected. In this method, by introducing a small number of correction light filter units, the spectral power distribution within the entire waveband to be detected can be obtained without using a large number of narrow waveband color filters. In addition, a light radiation measurement apparatus is disclosed.
