Problems solved by technology

When high-speed switching of the optical path is required, it is difficult for the galvanometer switching to meet the ideal performance requirements
This is because, firstly, the performance requirements of the galvanometer are high, the control is difficult, and the cost performance is low. The vibration is strong; Fourth, the price of the vibrating mirror is relatively high, and the most expensive vibrating mirror on the market can reach about 100,000 yuan

Abstract

The invention discloses an optical path rapid-switching device which comprises a lens fixing part, a cam part, an elastic piece, a mounting seat and a motor, wherein the lens fixing part and the cam part are all detachably mounted on the mounting seat; the cam part comprises a cam; a reflective lens is fixed at one end of the lens fixing part, and the other end of the lens fixing part is connected with one end of the elastic piece; a rolling wheel is arranged in the middle of the mounting seat; the rolling wheel is in contact with the circular arc section of the side wall of the cam under the tensioning force action of the elastic piece; when the cam rotates, the lens fixing part drives the reflective lens to rotate back and forth between two different positions, so that the reflection direction of the optical path incident on the reflective lens is changed. The optical path rapid-switching device is stable in operation, can flexibly regulate the angle of incidence of the incident light, can fully replace an oscillating mirror, and can further reduce the cost.

Description

technical field [0001] The invention belongs to the field of optical mechanics, and in particular relates to an optical path fast switching device. Background technique [0002] In the design of the optical light path, when it is necessary to quickly switch the propagation path of the light path, a mirror body must be used to switch the light path. According to this requirement, the galvanometer is often used for switching. When high-speed switching of the optical path is required, it is difficult to achieve the ideal performance requirements for the vibration mirror switching. This is because, firstly, the performance requirements of the galvanometer are high, the control is difficult, and the cost performance is low. The vibration is strong; Fourth, the price of the vibrating mirror is relatively high, and the most expensive vibrating mirror on the market can reach about 100,000 yuan. Contents of the invention [0003] The invention provides a fast optical path switch...
