Abstract:
A projection display apparatus includes a light valve that modulates illuminating light on the basis of image data to output the modulated light, an illuminating unit including a light source, and a plurality of optical members for illumination that generate the illuminating light on the basis of light from the light source to guide the illuminating light to the light valve, a projection lens that projects the modulated light from the light valve on a projection surface, and allows detection light to enter from a direction opposite to a travelling direction of the modulated light, and an imaging device that is disposed at a location optically conjugated with the light valve, and allows the detection light to enter through the projection lens. The plurality of optical members for illumination have optical property of reducing a noise component that affects the detection light and arises inside the illuminating unit.

Claim (Index 20):
The projection display apparatus according to  claim 1 , further comprising\n a light source unit emits invisible light, to provide coverage of at least a projection area on the projection surface with the invisible light for detection from a predetermined height, the projection area being an area projected by the projection lens, wherein the imaging device allows the invisible light diffused by hitting an object in vicinity of the projection area, as the detection light, to enter through the projection lens.
