实验原理

Using the working principle of interferometer interference frequency modulation, the light emitted by the light source is changed into interference light through the Michelson interferometer, and then the interference light irradiates the sample, the receiver receives the interference light with the sample information, and then the spectral diagram of the sample can be obtained by the computer software through Fourier transform.
