Embodiment Construction

[0014] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0015] Such as figure 1 As shown, the center alignment system between the optical target simulator and the spherical fairing includes 3 self-collimating optical systems (3), which are distributed in the simulator test dome (2) that is axisymmetric about the optical axis of the target simulator (1) superior. The optical axes of the three self-collimating optical systems intersect at one point, and this point is located at the theoretical spherical center position of the target simulator test dome cover. The centering system is used to achieve centering between the target simulator (1) and the seeker system (5), wherein the seeker fairing (4) is spherical, when the target simulator and the seeker When the spherical fairing achieves center alignment, the seeker spherical fairing and the simulator test dome should be concentric; the seeker thermal imager (6) is located ...

Abstract

The invention, which belongs to the technical field of the center alignment, discloses a center alignment system for an optical target simulator and a spherical radome. A problem that the existing center alignment method can not be used directly for center alignment between a target simulator and a seeker spherical radome can be solved. The system comprises three auto-collimation optical systems (3) that are distributed on a simulator testing spherical cover (2) in axial symmetry with an optical axis of the simulator; the optical axes of the three auto-collimation optical systems are intersected at one point that is located at a theoretical center of sphere of the testing spherical cover of the target simulator. According to the invention, center alignment system for an optical target simulator and a spherical radome of a seeker can be realized, so that clear imaging of the simulated target of the target simulator in the optical signal of the seeker can be realized.

Description

technical field [0001] The invention belongs to the technical field of center alignment, and mainly relates to an optical target simulator and a spherical fairing center alignment system. Background technique [0002] The target simulator tests the imaging performance of the seeker optical system by simulating a hardware-in-the-loop simulation target under laboratory conditions. During the test, there may still be a large center deviation between the target simulator and the seeker system after rough manual calibration. [0003] The center deviation can destroy the pupil coupling between the target simulator and the seeker system, resulting in problems such as image brightness reduction and poor image uniformity, making the seeker optical imaging system unable to perform ideal imaging. Therefore, before testing the imaging performance of the seeker optical system, it is necessary to accurately correct the center deviation between the target simulator and the seeker optical ...
