Abstract

The invention discloses a two-dimensional electric mirror adjustment device, relates to the technical field of beam control and overcomes defects that an existing fast steering mirror has a small rotation angle range and is high in manufacturing cost to realize automatic two-dimensional adjustment of a planar mirror. The device comprises a support base, a mirror seat, a planar mirror, a central shaft, a bearing press ring, a lens press block, two telescopic sliders, two slider guide seats, a knuckle bearing, two stepping motors, a backlash spring, an adjusting screw seat, an adjusting screw, two reset spring seats and two reset springs. Through threaded connection of the stepping motors and the telescopic sliders and limited guide of the slider guide seats, rotation movement of the stepping motors is converted into linear movement, further, the mirror seat and the mirror are directly driven by balls at the end parts of the telescopic sliders to deflect at a small angle, the cost is low, the two-dimensional electric mirror adjustment device can realize angle adjustment in a range of plus or minus 5-degree level through travel increase of a driver, and the adjustment range is increased by almost a hundred times than that of plus or minus 5' level of the fast steering mirror.

Description

technical field [0001] The present invention relates to the technical field of light beam control technology, in particular to a two-dimensional electric mirror device. Background technique [0002] In the optical system, in order to precisely control the propagation direction of the light beam, the optical elements must be adjusted precisely. However, affected by factors such as environmental temperature changes and stress release of structural parts, the ideal position of optical components is not unique under different environmental conditions. Therefore, for some optical systems that require high precision, it is required that the optical system must have a mirror whose angle state can be adjusted to compensate for the deviation of the optical path caused by changes in the external environment. [0003] Two-dimensional fast mirrors have the advantages of fast response speed, high pointing accuracy and high angular resolution, and are widely used in various optical path ...
