Embodiment Construction
[0039] Such as figure 1 As shown, the interferometer has four end faces a, b, c, and d, which can be set as two incident end faces and two outgoing end faces respectively. The front imaging objective lens 1 collects the energy from the target scene and forms an image on the primary image plane. The isosceles trapezoidal prism interferometer 2 is placed at the position of the primary image plane (that is, the focal plane position of the front imaging objective lens), the imaging light of the target scene is incident on the incident end a of the interferometer, and is divided into The two beams respectively pass through the reflective surface of the interferometer and then merge through the beam splitting surface. The combined two beams of light generate transverse shear and interfere at the position of the primary image plane. The imaging coupling mirror 3 is imaged on the photodetector 4 for reception.
[0040] The first part 5 of the incident light path of the incident end b...
