Stereo projecting equipment

The invention provides stereo projecting equipment which comprises a light source assembly, a first polarizing beam splitter, a second polarizing beam splitter, a third polarizing beam splitter, a fourth polarizing beam splitter, a first polarizing converter, a second polarizing converter, a first reflection type electrooptical modulator, a second reflection type electrooptical modulator and a projecting lens, wherein light emitted by the light source assembly is split into a first polarizing light beam and a second polarizing light beam by the first polarizing beam splitter, and the polarizing states of the two polarizing light beams are mutually vertical; the first polarizing light beam is reflected to the second polarizing light beam splitter by the first polarizing beam splitter; and the second polarizing light beam is sequentially transmitted through the first polarizing beam splitter and the second polarizing beam splitter. The invention has the advantages that a practical stereo projecting equipment sc
