Background

A projector is an optical instrument that magnifies the contour of a workpiece using an optical element and projects it onto a screen. It can be used for profile measurement by transmitted light, and also can be used for measuring the surface shape of a blind hole and observing the surface of a part by reflected light.

The traditional projector comprises a chip, a prism combination, a lens and a display screen, wherein the chip reflects light beams through the irradiation of a light source, transmits the light beams through the prism combination, and projects the light beams to the display screen through the lens for imaging. Because the imaging process of the traditional projector is simple, the projected image quality is directly blurred and rough due to the process of directly projecting the image to the lens through the prism combination, and the use mood of consumers is reduced.
