Problems solved by technology

[0002] When an object is irradiated by laser light, if the surface of the object is smooth or the color of the object is dark (such as the object is painted with black paint or the surface of the object is a mirror surface), the diffuse reflection of the laser on the surface of the object will be greatly weakened, resulting in The laser light is difficult to be collected
For example, when a camera that uses a laser as a compensation light source collects images, if the surface reflection characteristics of the collected object are poor, the quality of the collected image will be poor

Embodiment Construction

[0023] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0024] Such as figure 1 Shown, in a kind of embodiment of the present invention, strengthen the method for line laser light source intensity, comprise the following steps:

[0025] A lens group X1 is arranged in front of the laser emitting direction of the laser A1, and the lens group X1 compresses the laser light emitted by the laser A1 into a line laser M1 with a divergence angle of α1;

[0026] A lens group Xn is arranged in front of the direction in which the laser An adjacent to the laser An-1 emits laser light, and the lens group Xn compresses the laser light emitted by the laser An into a line laser Mn with a divergence angle of αn, the line laser Mn is in the same plane as the line lasers M1 to Mn-1.

[0027] The n is a positive integer not less than 2, that is, a combination of two or more lasers and lens groups, and n is 4 in this ...

Abstract

The invention discloses a method and a system for reinforcing a line laser light source and belongs to the technical field of laser light sources. A lens set X1 is arranged in front of the laser emitting direction of a laser A1, and the lens set X1 is used for compressing the laser emitted by the laser A1 into a line laser M1 with the divergence angle of alpha1; a lens set Xn is arranged in frontof the laser emitting direction of a laser An adjacent to a laser An-1, the lens set Xn is used for compressing the laser emitted by the laser An into a line laser Mn with the divergence angle of alpha n, and the line laser Mn is located on the same plane as the lasers M1- Mn-1; and n is a positive integer not less than 2. According to the method and the system in the invention, the intensity of the line laser can be remarkably enhanced, so that the laser can be more easily collected when being irradiated on an object with a smooth surface or a black surface.

Description

technical field [0001] The invention belongs to the technical field of laser light sources, and in particular relates to a method and system for enhancing the intensity of a line laser light source. Background technique [0002] When an object is irradiated by laser light, if the surface of the object is smooth or the color of the object is dark (such as the object is painted with black paint or the surface of the object is a mirror surface), the diffuse reflection of the laser on the surface of the object will be greatly weakened, resulting in The laser light is difficult to be collected. For example, when a camera using a laser as a compensation light source collects images, if the surface reflection characteristics of the collected object are poor, the quality of the collected images will be poor. Contents of the invention [0003] In view of the defects existing in the prior art, the technical problem to be solved by the present invention is to provide a method and sy...
