Five-rod mechanism, swinging mirror system and two-dimensional swinging mirror device

Abstract

The invention discloses a five-rod mechanism, and the mechanism comprises a first member, a second member, a third member, a fourth member, and a fifth member. One end of the first member is connected with the fifth member through a first rotating hinge, and the other end of the first member and one end of the second member are connected through a second rotating hinge. The other end of the second member and one end of the third member are connected through a first spherical hinge. The other end of the third member and one end of the fourth member are connected through a second spherical hinge, and the other end of the fourth member and the fifth member are connected through a third rotating hinge. The second member is driven by the first member to make pitching motion around the first rotating hinge, and the second member is driven by the third member and the fourth member to make orientation motion around the second rotating hinge. The mechanism is reasonable in arrangement, is compact in structure, and is small in size. Moreover, the swinging angle of the second member is big, and theoretically can reach a swinging range allowed by the first spherical hinge and the second spherical hinge. In addition, the invention also provides a swinging mirror system and a two-dimensional swinging mirror device.

Description

technical field [0001] The invention relates to the field of light beam control, in particular to a five-bar mechanism, a swing mirror system and a two-dimensional swing mirror device. Background technique [0002] The fast mirror is a technology developed in recent years for precise tracking, which is used to control the direction of the emitting and receiving optical axes and correct the change of the beam pointing. The fast reflector works between the light source or receiver and the target, and is an important part for adjusting and stabilizing the visual axis or beam pointing of the optical system. Relevant units at home and abroad are committed to the research of fast mirror systems, which have been successfully applied in astronomical telescopes, adaptive optics, space laser communications, and laser weapons. [0003] At present, the structural forms of fast mirrors are mainly divided into two structural forms with shafting and shafting. The shafted fast mirror adop...

AI Technical Summary

Problems solved by technology

The shafted fast mirror adopts the traditional mechanical shaft system, and the deflection of the mirror is driven by driving the mechanical shaft. It has the characteristics of a large range of motion, but it also has the problem of large volume.
