Projection ray machine with light modulation component and scanning galvanometer component and projector

The invention relates to the technical field of optical equipment, and provides a projection ray machine with a light modulation component and a scanning galvanometer component and a projector. The projection light machine with the light modulation part and the scanning galvanometer part comprises a light source part, the light modulation part and the scanning galvanometer part. The light source component emits light beams; the light modulation component and the scanning galvanometer component are sequentially arranged along a light path, and the light modulation component is used for modulating a light beam. The projector is used for overcoming the defects that in the prior art, a projector is high in cost and not easy to produce, high-quality pictures can be projected without depending on a high-resolution light modulation component, the cost of the projector is reduced, a galvanometer does not need to be imported to the outside, the manufacturing difficulty of the projector can be reduced, and the producti
