ON THE TSVD METHOD IN TWO-BEAM INTERFERNCE SPECTROSCOPY
双光束干涉光谱术中的TSVD方法

The results of applying the theory of Hilbert and Schmidt fo two-beam interferencespectroscopy are studied.It is found that the essence of truncating the singular values is to cut off apart of the inverse matrix of the integral kernel.This explains it clearly that why the SNR is better inthe higher wave number region when TSVD method is applied to two-beam interferometer.
