Abstract
Transfer function is a very important parameter to evaluate the system performance, and it is one of the key methods to process and analyze information. First, the feasibility of this method is analyzed by the theory simulation in this paper. Second, the median is selected to filter the noise in the spectral data by comparing median filtering and Db3 wavelet filtering results. And then, the transfer function method is used on the data processing that captured by a linear CCD spectrometer. The experimental results show that the spectral data processing method base on the transfer function given in this paper is reasonable. This method can further improve the accuracy and the resolution of the instrument, and can make it possible to get a wide application of the CCD spectrometer.
