Fresnel lens target device used for laser shooting

The invention relates to a Fresnel lens target device used for laser shooting. The Fresnel lens target device comprises a laser gun, a target surface, an image processing device and a shot indication computer. The target surface is of a transparent structure, and a shooting target graph is arranged on the target surface. A Fresnel lens is attached to the back face of the target surface. The image processing device is arranged at the focus of the Fresnel lens and connected with the shot indication computer through a data line. The target surface, the Fresnel lens and the image processing device are all arranged in a target box. The Fresnel lens is arranged in front of an image collection camera lens, light rays perpendicularly emitted in can be effectively focused, the image processing device is arranged at the focus of the Fresnel lens, and therefore accurate collection is achieved for the laser gun without interference of external parasitic light.
