Filter structure and optomechanical system

Abstract

The invention discloses a filtering structure and an optical-mechanical system. The filtering structure comprises a shaft core block and a first arc-shaped filter. The shaft core block is used for being connected with an actuator so as to be driven by the actuator to swing in a reciprocating mode. The first arc-shaped filter is connected with the shaft core block and is provided with a first arc line. A center angle corresponding to the arc line is less than 360 degrees. The optical-mechanical system comprises a light source set, the filtering structure and the actuator. The light source set is used for generating a light beam and is arranged relative to the filtering structure. The actuator is connected with the shaft core block of the filtering structure so as to drive the filtering structure to swing in the reciprocating mode. The arc-shaped filter of the filtering structure can swing in the reciprocating mode so as to change the wavelength of a light beam, and can swing to a position so as to enable the light beam not to penetrate through the arc-shaped filter. The filtering structure can be applied in the optical-mechanical system. The optical-mechanical system can be applied in a projector and enables the projector to switch between output of two-dimensional images and output three-dimensional images.

Description

technical field [0001] The present invention relates to a filter structure and an optical-mechanical system, and in particular to a reciprocatingly oscillating filter structure and a reciprocally oscillating filter structure. Background technique [0002] Compared with traditional two-dimensional (2D) projection technology, three-dimensional (3D) projection technology (or called stereoscopic projection technology) can bring users the feeling of space as if they are in the image, so it is more and more popular among users. favorite. [0003] The 3D projection technology used at this stage is more commonly called "color lens passive 3D projection technology". Projectors using this projection technology include a color filter (color filter), or color wheel, that rotates continuously in the same direction, and the color filter has a right-eye filter area and a left-eye filter area. light zone. With the rotation of the color filter, the light beam projected by the light source...
