Optical processing system, optical processing system parameter determination method and terminal

The invention provides an optical processing system, an optical processing system parameter determination method, a terminal, an optical processing system imaging element, a diaphragm and a collimating element. The imaging element is used for imaging the laser light-emitting surface on the second side of the imaging element, the optical axis of the imaging element is perpendicular to the laser light-emitting surface and penetrates through the center of the laser light-emitting surface, and the laser light-emitting surface is located on the first side of the imaging element; the diaphragm is arranged at the position where the laser light-emitting surface forms a real image on the second side of the imaging element, and the light passing size of the diaphragm is the same as the size of the laser light-emitting surface after the real image is formed on the second side of the imaging element; and the collimating element is used for collimating the light beam passing through the diaphragm.
