Abstract

The invention discloses a laser focusing system. The system comprises a laser emitter, a light intensity regulator, an electronic gate, a laser focusing device, a CMOS camera and a mobile terminal, the laser emitter is used for emitting laser; the light intensity regulator is used for regulating the intensity of the laser; the electronic gate is used for controlling the opening and closing of thelaser light path; the laser focusing device is used for focusing laser; the CMOS camera is used for receiving a control signal of the mobile terminal to capture a laser spot in a laser transmission direction and uploading a laser spot image to the mobile terminal; the displacement table is used for realizing movement of the CMOS camera; and the mobile terminal is used for processing the laser spotimage, acquiring the focal plane position of the laser beam and controlling the moving distance of the CMOS camera and the displacement table. According to the invention, manual debugging is not needed, and automatic focusing can be realized.

Description

technical field [0001] The invention relates to the field of lasers, in particular to a laser focusing system. Background technique [0002] Laser has high monochromaticity and good directionality. It can be combined with multiple disciplines and applied in many technical fields, such as optical fiber communication, laser processing, laser measurement, laser surgery, etc. And these technologies can be divided into two categories: energy applications of lasers and information applications of lasers. [0003] When applying laser energy, the core of its technology is the control of laser light intensity and laser spot size. Among them, most of the application of laser energy is under the condition of laser focusing. At present, common laser autofocus technologies include the autofocus technology based on the gray-scale center of gravity method and the autofocus technology based on the Hough circle transform. [0004] However, in actual application, the autofocus technology b...
