Abstract:
An image projection apparatus includes a light source unit emitting illumination light, a first optical modulation unit, a second optical modulation unit, a third optical modulation unit, a fourth optical modulation unit, a color separating-combining system, and an illumination optical system. The illumination optical system includes a polarization conversion unit and a reflection unit including a mirror arranged on a position different from that of the polarization conversion unit on an optical path from the light source unit to the fourth optical modulation unit and a mirror arranged on an optical path from the fourth optical modulation unit to the front side color separating unit.

Claim (Index 1):
An image projection apparatus comprising:\n a light source unit configured to emit illumination light including first color light, second color light, and third color light of which wavelengths are different from each other; a first optical modulation unit configured to modulate the first color light; a second optical modulation unit configured to modulate the second color light; a third optical modulation unit configured to modulate the third color light; a fourth optical modulation unit as a transmissive liquid crystal panel unit configured to modulate the illumination light; a color separating-combining system configured to guide the first color light to the first optical modulation unit, to guide the second color light to the second optical modulation unit, to guide the third color light to the third optical modulation unit, and to combine the light from the first optical modulation unit, the light from the second optical modulation unit, and the light from the third optical modulation unit; and an illumination optical system configured to illuminate the fourth optical modulation unit with the illumination light and to guide light from the fourth optical modulation unit to the color separating-combining system, wherein, in a case where a color separating unit arranged on a most light source unit side on an optical path from the light source unit to the color separating-combining system in color separating units included in the color separating-combining system is regarded as a front side color separating unit, the illumination optical system includes a polarization conversion unit configured to convert a polarization direction of the illumination light from the light source unit into a predetermined polarization direction and a reflection unit including a mirror arranged on a position different from that of the polarization conversion unit on an optical path from the light source unit to the fourth optical modulation unit and a mirror arranged on an optical path from the fourth optical modulation unit to the front side color separating unit.
