| Abstract: | Aimed at the demands on spectral measurement and application of LED and based on the theories relating to spectral and color measurement in photometry and colorimetry,this paper introduces a spectral measuring and analyzing system,which uses plane reflected grating as light splitting device and linear CCD as multi-channel photoelectric conversion device and can measure the spectral parameters of LED and calculate peak wavelength reflecting the luminescence character and domain wavelength corresponding to feel of eyes.Moreover,this paper carries out discussions and demonstration on the related theories and testing methods in practice. |
