[0019] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings, but it is not limited thereto. Any modification or equivalent replacement of the technical solution of the present invention without departing from the spirit and scope of the technical solution of the present invention should be covered by the present invention. within the scope of protection.
[0020] Design a zoom conformal optical system with a focal length of 120mm and an F / # of 2 in the optical design software CodeV as the initial structure. The parameters of the conformal optical system are shown in Table 1. The structure diagram is as follows figure 2 As shown: the front end is an ellipsoidal conformal fairing with a diameter-to-length ratio of 1, and the two pieces behind it are fixed correctors. The optical system is a Cassegrain structure plus five lenses, which are composed of Ge, ZnS, Ge, Made of ZnS and Si materials, the last lens...
