Claim 11:
12. A 3D apparatus, comprising a projection apparatus and a polarizing and splitting device, wherein the polarizing and splitting device comprises a prism unit and a lens assembly, and is configured to convert light emitted from the projection apparatus into polarized light through the prism unit and the lens assembly, and project the polarized light on a screen,
wherein the projection apparatus comprises:, a light source device and an opto-mechanical device, wherein the opto-mechanical device comprises at least one lens and is configured to receive homogeneous light from the light source device, process the homogeneous light through the lens, and then output the homogeneous light,
wherein the light source device comprises:
a laser generation unit configured to output laser light;
a light modification element disposed in a light guide unit or between the light guide unit and a homogenizing unit and configured to cause an angular distribution of the laser light uniform and continuous;
the light guide unit, configured to receive the laser light output by the laser generation unit and guide the laser light to the homogenizing unit; and
the homogenizing unit, configured to receive the laser light from the light guide unit, and homogenize and output the laser light.
