[0023] In order to clearly illustrate the technical features of the solution, the solution will be described below in conjunction with the accompanying drawings and specific implementation methods.
[0024] figure 2Shown is a top view of a scanning interferometer device for imaging Fourier transform spectrum measurement according to the present invention: the light emitted by the target to be measured is collected by the light collection system at the front end of the imaging Fourier transform spectrometer and collimated into an incident beam 1, 1 enters the spectrometer and shoots to the cube beam splitter 2; the reflected beam passing through 2 is reflected by the 45° plane mirror 5, and the optical path is folded by 90° and shoots to the compensation plate 6. After the beam passes through 6, it is perpendicular to the double-sided plane reflection The reflective surface on one side of the mirror 7 is finally vertically reflected by the fixed 7, and returns to 2 along the o...
