Example Embodiment
[0013] The content of the present invention will be further described below with reference to the accompanying drawings and embodiments, but the actual production structure of the present invention is not limited to the following embodiments.
[0014] Referring to FIG. 1, the structure of the polarization imaging spectrometer includes a front polarization interferometer 2, an imaging lens group 3, an area array detector 4 and other parts. The signal output terminal of the area array detector 4 is connected with the signal input terminal of the computer signal processing system through a connecting wire. In order to prevent stray light, a fused silica glass window (number 11) and a cut-off filter (number 12) are added in front of the front polarization interferometer 2.
[0015] The structure of the polarization interferometer 2 is shown in FIG. 2, which includes three parts: a polarizer 21, a Savoy polarizer, and an analyzer 24. The Sava polarizer is composed of two natural uniaxi...
