Problems solved by technology

[0003] However, limited by space and driving methods, the optical actuators on the market all use optical reflective optical elements, but only transmissive optical elements can be used in the lens group, so the products that can be used are different. There are limitations, and it is impossible to choose a suitable optical actuator for different needs

Abstract

The invention discloses an optical actuator, which comprises a substrate, a load bearing seat, an optical element, two rotating structures and an actuating assembly. The load bearing seat is arranged on the substrate; the optical element is arranged on the load bearing seat; the rotating structures are connected to both sides of the load bearing seat respectively; and the actuating assembly drives the load bearing seat to make the load bearing seat rotate at one angle.

Description

technical field [0001] The present invention relates to an actuator, in particular to an optical actuator. Background technique [0002] Generally speaking, optical actuators are used in projection systems to achieve the functions of increasing pixels and smoothing images. The projection system can be mainly divided into an image generating device and a projection lens group. The image generation device generates images by technologies such as digital micro-mirror devices (Digital Micro-mirror Device, DMD), three liquid crystal panels (3LCD) or liquid crystal on silicon panels (LCoS), and the projection lens group projects the images onto the screen. The optical actuator is arranged between the image generating device and the projection lens group, and swings to achieve the functions of increasing pixels and smoothing images. [0003] However, limited by space and driving methods, the optical actuators on the market all use optical reflective optical elements, but only tra...
