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 20):
The image projection apparatus according to  claim 1 ,\n wherein the illumination optical system includes a lens array configured to form a plurality of first light source images, a first condenser lens unit arranged between a first area in which the plurality of first light source images is formed and the fourth optical modulation unit, a second condenser lens unit arranged between a second area in which a plurality of second light source images different from the plurality of first light source images is formed and the first optical modulation unit, and a relay lens unit configured to form light from the plurality of first light source images as the plurality of second light source images, wherein the relay lens unit includes a first relay lens unit arranged on an optical path between the first area and the fourth optical modulation unit and a second relay lens unit arranged on an optical path between the fourth optical modulation unit and the second area, and wherein, in a case where a focal length of the second condenser lens unit is defined as F2, a focal length of the second relay lens unit is defined as FR2, and an air conversion length from a principal plane of the second condenser lens unit to a principal plane of the second relay lens unit is defined as DR2, a following relationship is satisfied:\n 0.7\u2264 DR 2/( FR 2+ F 2)\u22641.3.
