Design and implementation of a spectral fitting system
In order to improve the efficiency of spectral data analysis and fast synthesis of the target spectra using multiple LEDs of different bands,a spectral fitting system is proposed,in which a spectral database is established and data extraction of the target spectral curves is carried out using the upper computer,the optimal parameters of the drive current are solved using an opti-mization algorithm,and the actual fitting of the target spectra is realized by the lower computer.The analysis of the spectral acquisi-tion results shows that the fitting excellence of the actual output spectral curve to the AM1.5 spectrum as well as the randomly plot-ted spectral curve is 0.69 and 0.77,respectively,which is able to better reflect the trend of the target spectrum.
