Illumination optics and image projecting apparatus having thereof |
摘要 |
An illumination optics includes a plurality of light source sections for emiting light beams and a time sharing color separation device having a plurality of color filters. The color filters are rotationally moved so as to cross optical paths of the emitted light beams from the light source sections, thereby separate the emitted light beams to enter there into different color light beams in a time-sharing state. The reference axes of the emitted light beams to enter the time sharing color separation device are separated from each other, and the color filters are formed so that border lines of the adjacent color filters cross the reference axes approximately simultaneously at the time of rotation.
