Holographic sight

The invention provides a holographic sight. The holographic sight comprises a sight shell, a light source and a holographic waveguide element; the light source and the holographic waveguide element are arranged in the sight shell; the holographic waveguide element comprises an incident holographic grating, an outgoing holographic grating and waveguide; the incident holographic grating and the outgoing holographic grating are arranged at two ends in the length direction of the waveguide; an optical axis of the outgoing holographic grating is arranged in parallel with a clamping groove in the scope shell; the outgoing holographic grating is a hologram with an aiming and partition pattern; and the light emitted by the light source is injected by the incident holographic grating, transmitted through the waveguide, and then emitted out by the outgoing holographic grating. The holographic sight can reduce the number of parts of the sight, so that the structure of the sight is simpler, the volume of the sight is red
