Claim 5:
6. The quadrilateral common-path time-modulated interferometric spectral imaging device according to claim 1, further comprises: a convergence module, a detection acquisition module and a signal processing module; a target surface of the detection acquisition module is located on a back focal plane of the convergence module, and the signal processing module is connected with the detection acquisition module; the convergence module is configured to form interference from the beam exited by the quadrilateral common-path interferometer, and image it onto the detection acquisition module; the detection acquisition module is configured to sample and collect an interference fringe signal at different moments, and convert it into an electrical signal to obtain detection information; the signal processing module is configured for spectral restoration according to the detection information to obtain a spectral information.
