Abstract

The invention belongs to the technical field of optical nacelle image acquisition control and particularly relates to a view field switching and focusing device. The device mainly comprises a body, amotor, a speed reducer assembly, a V-shaped guide seat with a magnet, a rotation switching assembly, a camera objective assembly and a rotation force sealing assembly. The device achieves a high-precision view field switching function and a high-precision focusing function under wide and narrow view fields separately through a direct-current motor, has a compact structure and is small in size andhigh in reliability; through application of small optical mechanical components, the diameter and length of a nacelle can be reduced, the weight of the nacelle is reduced, and the aiming precision ofthe nacelle and the flight performance of the aircraft are improved.

Description

technical field [0001] The invention belongs to the technical field of optical pod image acquisition and control, and in particular relates to a field of view switching and focusing device. Background technique [0002] The laser irradiation pod is an important part of the laser-guided bomb weapon system. It is a high-precision photoelectric tracking plug-in system. Targets such as industrial facilities can be searched, discovered, identified, tracked and laser pointed out, and airborne weapons can be guided to achieve precise strikes. [0003] The optically stabilized platform is an important part of the laser irradiation pod. The combination of optics and stabilized platform involves laser collimation, TV camera, multi-spectral separation, illumination adjustment, field of view switching and focusing, image rotation elimination, and system self-test and self-calibration. and line-of-sight stabilization. Among them, the field of view switching and focusing device can prov...
