Embodiment Construction
[0027] The present invention is described in detail below in conjunction with accompanying drawing:
[0028] The invention system consists of borrowing a high-precision two-axis horizontal or two-axis vertical lathe as a platform, such as figure 1 As shown, each of its two rotation axes is 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, infrared collimator and internal focusing centering device , the object plane of the optical lens faces the collimator and the inner focusing and centering instrument; the focal plane component is fixed on another optical centering adjustment device, and its focal plane faces the direction of the collimator and the inner focusing and centering instrument.
[0029] The method of the invention specifically comprises the following steps:
[0030] 1. Adjust the parallelism between th...
