Abstract: This application discloses a projector, a camera module, and a terminal device. The projector includes a light source, a first optical device, a second optical device, and a projection device. The light source emits a first light ray having a first polarization direction to the first optical device. The first optical device transmits the first light ray. The second optical device turns the transmitted first light ray into a second light ray having a second polarization direction. The first optical device reflects the second light ray. The projection device diffracts the reflected second light ray, to form a projected light beam.
