Abstract

The invention discloses an adjustable annular light beam generating mechanism, which includes a driving motor, a transmission worm, a fixed base, a rotating bearing, a rotating part, a peripheral reflector base, a peripheral reflector fixing seat, a peripheral reflector, a central reflector The mirror base, the center reflector fixing seat and the center reflector, the drive motor is connected with the transmission worm, and the transmission worm is then meshed with the gear arranged on the rotating part, and the rotating part is arranged on the On the fixed base, the central reflector base is arranged in the middle of the rotating component. The invention realizes the time-sharing use of the mirror surface of the optical path, and has the advantages of adjustable blocking ratio, good stability, adjustable rotating speed, etc., and can effectively enhance the light beam utilization rate and the strong light resistance ability of the mirror surface.

Description

technical field [0001] The invention relates to the technical field of Cassegrain systems, in particular to an adjustable annular beam generating mechanism. Background technique [0002] The Cassegrain system consists of a parabolic primary reflector and a hyperboloid secondary reflector. It is a double-reflection folding system that can effectively shorten the length of the lens barrel and has no chromatic aberration. It is widely used in various tracking, detection and launch systems. However, due to the obstruction in its center, the transmission of ordinary solid light beams through it will cause energy loss. At the same time, in complex optical systems, the improvement of beam energy is limited by the ability of some mirrors to withstand strong light. Contents of the invention [0003] The invention overcomes the deficiencies of the prior art and provides an adjustable annular light beam generating mechanism, which is used to solve the technical problems that the cen...
