Further, the measuring assembly includes a diffusely reflecting plate 9, a stand 10, and a scale drawing 11.
The diffuse reflection plate 9 is vertically fixed on the rack 10, and the scale drawing 11 is adhered to one side surface of the rack 10.
Wherein, the scale drawing 11 is a cross scale for measuring the spot diameter of the laser generated on the diffuse reflection plate 9.
Specifically, when the scale drawing 11 calibrates the spot diameter measured each time, the number of imaging pixels corresponding to the same scale length is the same, that is, the length geometric relationship between the spot diameter and the imaging pixels is determined.
Based on the geometric relationship, after the scale drawing 11 is removed, laser is focused on the diffuse reflection plate 9, and then when the laser forms a clear light spot image in the camera, the actual light spot size is calculated by measuring the number of occupied pixels of the light spot.
It should be noted that, since the laser is emitted on the ordinary board, the ordinary board will be ablated, so the diffuse reflection board 9 is used, so that the laser emitted on the diffuse reflection board will be reflected in all directions, and the laser will not ablate the diffuse reflection board 9.
