[0027] The present invention will be described in detail below in conjunction with the drawings:
[0028] The system of the invention is composed of borrowing a high-precision two-axis horizontal or two-axis vertical lathe as a platform, such as figure 1 As shown, the two rotating shafts are each fixed with an optical centering adjustment device that can realize four-degree-of-freedom adjustment, and the optical lens is fixed on the optical centering adjustment device close to the surface source black body, the infrared collimator and the inner focusing center. , The object plane of the optical lens faces the collimator tube and the inner focus center; the focal plane assembly is fixed on another optical center adjustment device, and the focal plane faces the collimator tube and the inner focus center.
[0029] The method of the invention specifically includes the following steps:
[0030] 1. Adjust the parallelism between the docking reference plane of the focal plane component and ...
