Problems solved by technology

When it is necessary to change the generated optical signal, it is generally necessary to replace different components that generate structured light, and the structured light generated by the replaced component does not completely match, and it is difficult to meet the needs of the light source.
In the existing scheme, the optical path is not easy to change, and the required optical devices take up a lot of space, resulting in large equipment and not portable

Abstract

The invention provides a structured light projection device and optical equipment. The structured light projection device comprises a laser generation module, a diffractive optical element DOE and a reflection module, wherein the DOE is arranged on a light path of the laser beam; the reflection module is arranged on a light path of the structured light; the laser generation module is used for generating a laser beam; the DOE is used for generating structured light according to the laser beam; and the reflection module is used for reflecting the structured light. By implementing the embodiment of the invention, various parameters of structured light projection can be effectively adjusted so as to meet the optical requirements under different conditions and change the optical path to reduce the volume of the optical equipment.

Description

technical field [0001] The present application relates to the field of optical measurement, in particular to a structured light projection device and optical equipment. Background technique [0002] With the in-depth research and wide application of structured light applications in the field of optics, structured light projection devices or structured light projection components are also becoming more and more perfect. The principle of structured light involved in this technology generally produces an optical signal with certain structural characteristics (ie, structured light) and projects it onto the target object, and then acquires the image of the target object for the next step of measurement and other operations. Among them, the link of generating the required structured light is a very important step in the whole measurement process, which affects the subsequent data collection. At present, the components that generate structured light are basically fixed, and can ge...
