| 摘要 |
The present invention relates to a projection apparatus in which a beam of light from light source means is separated into beams of two polarized components by a polarization separator, and the direction of polarization of one of the separated beams of two polarized components is caused to coincide with the direction of polarization of the other beam of light through polarizing rotatable means, whereafter the two beams of light are condensed by a condenser of which the refractive power differs between two directions orthogonal to each other, a projected image is irradiated with the beam of light passed through the condenser and the projected image is projected onto a predetermined surface by a projector.
