Laser quality detection practical training instrument

The utility model discloses a laser quality detection training instrument. The laser quality detection training instrument comprises a laser; the laser device is installed on the lifting device, and the lifting device can drive the laser device to ascend and descend in the vertical direction; the light spot receiving part is made of a transparent material and comprises a rough first surface and asmooth second surface, and the first surface faces the laser device and receives laser emitted by the laser device to form a light spot; the imager directly faces the second surface and is used for collecting light spots and forming an image; the control terminal is connected with the imager and analyzes the image to obtain an energy distribution image of the light spot image; the position adjusting device can drive the light spot receiving part and the imager to be close to or far away from the laser; therefore, the imager can acquire images at different positions and the images are processedby the control terminal t
