Multi-axis optical rotating device

Abstract

The invention relates to a multi-axis optical rotating device, and the technical key points are that the device comprises a housing; a carrier used for bearing an optical path adjusting element for adjusting the angle of an optical path and can rotate around a first rotating shaft and a second rotating shaft relative to the shell respectively; a light path adjusting circuit board fixed with the carrier; an elastic supporting assembly connected between the shell and the carrier so that the carrier is suspended in the middle in the shell, wherein the carrier rotates around the first rotating shaft and the second rotating shaft respectively, the rotating stroke is limited, and the elastic supporting assembly is used for conducting a circuit between the shell and the light path adjusting circuit board; a lower limiting plate fixed to the shell and used for limiting the carrier to linearly move along a third shaft, and the third shaft is perpendicular to the plane where the first rotating shaft and the second rotating shaft are located; a driving assembly; and a sensing assembly. According to the invention, the problem that the focusing reliability of an optical axis turning product is reduced is solved, and the optical path offset is realized by driving the angle offset of the optical filter, so that the super-resolution function and the function of compensating unstable imaging are achieved.

Description

technical field [0001] The invention relates to an optical focusing system, in particular to a multi-axis optical rotation device, which can be adapted to carry an optical refraction module, including optical filters, etc., and can also be extended to mount an optical lens or other optical components. The resolution is improved by angular offset and the compensation function for unstable imaging is achieved by angular offset. Background technique [0002] Generally speaking, most of the voice coil motors commonly seen on the market move in a straight line. Whether it is the focus motor (AF) or the anti-shake system motor (OIS), most of them are used to carry optical components for translation to achieve the required optical effect. Limited by the volume and height requirements of digital products on the market, linear optical path products need to be turned to reduce the size of the original equipment or components, that is, the turning of the optical axis is realized throug...
