Dual-axis control tracking and focusing device with fixed reflecting surface and mirrored surface arrangement method

Abstract

The invention discloses a dual-axis control tracking and focusing device with a fixed reflecting surface and a mirrored surface arrangement method, and belongs to the field of optoelectronic technology. At least two fixed brackets are disposed side by side. An arc-shaped frame is disposed on an upper portion of the fixed bracket. Two ends of a plurality of strip-shaped reflecting mirror surfaces disposed parallelly are respectively fixed to two arcs so as to form a reflecting groove. Telescopic brackets are disposed two sides of the fixed bracket through rotating shafts. The other ends of thetwo telescopic brackets disposed on each of the fixed brackets are fixedly connected to a receiver at a connecting portion. The mirror center lines of all mirrored surfaces of the reflection grooves are located on the same virtual cylinder surface. The mirror inclined angles of the mirrored surfaces are different, and the reflected wave focus point trajectories for the parallel incident waves arealso located on the virtual cylinder surface. A control system controls the expansion and rotation of the telescopic bracket according to the detected changes of the incident wave angles and drives areceiver to move on the trajectory of the virtual cylinder surface so as to capture a reflected wave focus line.

Description

technical field [0001] The invention relates to a dual-axis control tracking focusing device with a fixed reflecting surface and a method for arranging a reflecting mirror, which belong to the field of optoelectronic technology, and in particular relate to a focusing and collecting device for light energy and electromagnetic energy. Background technique [0002] For electromagnetic waves with distant signal sources, the energy flow density obtained by the receiving end is relatively low (for example, the signal transmitted by a communication satellite to the ground is relatively weak, and the radiation intensity of sunlight reaching the ground is relatively low), so it needs to be gathered by some equipment to be used . However, the current tracking and control methods of the aggregation technology are complicated, basically relying on the rotation of the overall structure to capture signal waves or sunlight to achieve the function of focusing and collecting. The complex str...
