Embodiment Construction

[0026] The present invention is described in detail below in conjunction with accompanying drawing:

[0027] 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. The optical lens is fixed on the optical centering adjustment device close to the collimator and the inner focusing centering device. Super-direction collimator and internal focusing and centering instrument; the focal plane component is fixed on another optical centering adjustment device, and its focal plane super-directs to the direction of collimator and internal focusing and centering instrument.

[0028] The method of the invention specifically comprises the following steps:

[0029] 1. Adjust the parallelism between the docking reference plane of the focal plane component and the foc...

Abstract

The invention provides a combined adjusting and jointing method and a combined adjusting and jointing mechanism for a visible light imaging system and an imaging focal plane. The problem that the accuracy of perpendicularity between an optical axis of an optical imaging system and the imaging focal plane, the accuracy of an overlap ratio between the optical axis of the optical imaging system and the central normal of the target surface of the imaging focal plane and the accuracy of an overlap ratio between the image plane of the optical imaging system and the imaging focal plane in the conventional image plane jointing process cannot be ensured is mainly solved. By once clamping of a high-accuracy double-shaft lathe, a set regulation aim is fulfilled, the set regulation accuracy is achieved, and meanwhile, the jointing reference surface of a focal plane component and the end face of an optical lens mounting flange are turned, so that the parallelism between two planes is ensured, and an assembly error, which is caused by a previous assembly link, of the focal plane component and an optical lens is completely eliminated.

Description

technical field [0001] The invention relates to a method and mechanism for realizing high-precision combined adjustment and docking of a visible light imaging system and a focal plane. Background technique [0002] The camera composed of the visible light optical imaging system and the focal plane is an important payload of aircraft in the aviation and aerospace fields, providing video images and high-resolution pictures for various tasks, especially various high-resolution earth observation cameras. This type of long focal length optical The system has very high requirements on the perpendicularity between the optical axis of the optical system and the imaging focal plane, the coincidence degree between the optical axis and the normal line of the target surface of the imaging focal plane, and the coincidence degree between the image plane of the optical system and the imaging focal plane. Ensuring the above-mentioned index requirements has become an important link in determ...
