Problems solved by technology

[0003] However, when the diffraction element realizes the point-like spot superposition, there are restrictions on the wavelength of the light source and the type of light source; the superposition of the light spot through the placement angle of the light source will increase the structure of the entire optical system, making the structure not compact and the size of the light outlet large

Abstract

The invention discloses a laser module, a laser device, and a laser insertion beam splitting system and method, and relates to the technical field of laser shaping output, the laser module comprises a laser light source and a micro lens array arranged on the light emitting side of the laser light source, the incident plane of the micro lens array is a hyperboloid, and the micro lens array is used for splitting and emitting incident laser beams at an included angle. And the laser beams are split and emitted at an included angle to form different light spots. The laser beam is split through the micro-lens array, and the obtained light spots are diversified in form, can meet different requirements and are high in flexibility. Moreover, the beam splitting of the laser beam can be realized only by arranging the micro-lens array, so that the laser module is compact in structure, small in size and low in cost.

Description

technical field [0001] The present application relates to the technical field of laser shaping output, in particular, to a laser module, a laser device, and a laser stitching and beam combining system and method. Background technique [0002] Superimposed spot scanning is a commonly used light scanning application technology. The superposition of spot in the existing laser radar application is mainly realized by the diffraction element or the swinging light source. When the diffraction element is used, the non-interfering diffraction pattern is generated in the far field by means of independent irradiation of incoherent light, and the joint beam is realized. By swinging the light source, the light source can be irradiated at different angles, and the beams of different angles can be stitched together. [0003] However, when the diffraction element realizes the superposition of spot-like spots, there are restrictions on the wavelength of the light source and the type of the ...
