Precise two-dimensional image stabilization platform

Abstract

The invention relates to a precise two-dimensional image stabilization platform. The platform comprises a base, a lower-layer movement part and an upper-layer movement part, wherein the lower-layer movement part and the upper-layer movement part are arranged on the base in a laminated mode, and the lower-layer movement part is connected with the base through a hinge and can only achieve bidirectional movement in one direction; the upper-layer moving part is connected with the lower-layer moving part through a hinge and can only realize bidirectional movement in the other direction, and the moving direction of the lower-layer moving part is perpendicular to the moving direction of the upper-layer moving part; the upper-layer moving part is provided with a light through hole used for fixing an image stabilization optical assembly. The precise two-dimensional image stabilization platform provided in the technical scheme is simple in principle, compact in structure and small in coupling error, and can effectively solve problems that an existing tandem platform cannot respond to image stabilization operation synchronously in two directions, rigidity is relatively poor, image stabilization frequency is limited, and when a parallel platform moves simultaneously in two directions, coupling error is generated, image stabilization efficiency is poor, and image stabilization motion precision is reduced.

Description

technical field [0001] The invention relates to the technical field of optical image stabilization, in particular to a laminated micro-displacement two-dimensional precision image stabilization platform. Background technique [0002] With the continuous improvement of the requirements for the use of photoelectric surveillance, tracking, remote sensing, reconnaissance systems and precision strikes, the requirements for the stabilization of optical images are becoming increasingly strict, so it is urgent to improve optical image stabilization technology. Since the carrier is easily affected by environmental disturbances during flight, the local mirror groups of the optical system move relatively, and the position of the optical axis deviates, resulting in blurred images collected. At this time, it is necessary to add an optical image stabilization system to the imaging system. The image stabilization actuator adjusts the partial mirror group in real time to ensure clear imagin...
