Beam combination debugging method of laser display ray machine and test equipment

The invention discloses a beam combination debugging method of a laser display ray machine and test equipment. According to the method, during debugging, a preset distance is formed between the light outlet of the product and the target surface of the camera through the adjusting component, and the preset distance is equal to the actual working distance during product design. One path of light emitted by the laser is subjected to beam combination and defocusing, then a light spot falls on a target surface, the size of the light spot is adjusted to a preset size, and the light spot is shot by the camera. And then the light spot is used as a reference light spot, and light spots emitted by the lasers of other paths are sequentially adjusted to be aligned to the reference light spot until debugging is completed. Therefore, the beam combining standard can be quantified, the beam combining quality is improved, and the image quality of scanning display is further improved. 本申请公开一种激光显示光机的合束调试方法及测试设备。该方法调试时，通过调节部件使得产
