Abstract:
1. A stereoscopic projection device, comprising: a first light source module, comprising: a second light source module, comprising: a dichroic mirror, wherein the first light source module and the second light source module are respectively disposed at different sides of the dichroic mirror, and the dichroic mirror splits the first light beam, the second light beam, the third light beam, and the fourth light beam into first portions and second portions, guides the first portions of the first light beam, the second light beam, the third light beam, and the fourth light beam to a first optical path, and guides the second portions of the first light beam, the second light beam, the third light beam, and the fourth light beam to a second optical path; a first optical module disposed on the first optical path for guiding and modulating the first portions of the first light beam, the second light beam, the third light beam, and the fourth light beam passing along the first optical path to form a plurality of first image light beams with different images; a second optical module disposed on the second optical path for guiding and modulating the second portions of the first light beam, the second light beam, the third light beam, and the fourth light beam passing along the second optical path to form a plurality of second image light beams with different images; and a beam-combining prism for guiding the first image light beams and the second image light beams to a lens.
