Abstract:
A projection display unit ( 1 ) includes a projection optical system ( 10 A), a polarization separation device ( 15 ), and a detection optical system ( 10 B). The projection optical system includes an illuminator ( 11 ), a projection lens ( 16 ), and a light valve ( 12 ) that modulates illumination light supplied from the illuminator on the basis of an image signal, and outputs the modulated illumination light toward the projection lens. The polarization separation device ( 15 ) is disposed between the light valve and the projection lens. The polarization separation device separates entering light into a first polarized component and a second polarized component, and outputs the first polarized component and the second polarized component in respective directions that are different from each other. The detection optical system includes an imaging device ( 13 ) and a reduction optical system ( 14 ). The imaging device is disposed in a position that is optically conjugate with a position of the light valve. The reduction optical system is disposed between the imaging device and the polarization separation device. The imaging device receives, via the projection lens and the polarization separation device, light based on detection invisible light. A transmittance adjuster is provided between the polarization separation device and the imaging device. The transmittance adjuster adjusts transmittance of at least part of a bundle of passing light rays derived from the invisible light.

Claim (Index 20):
The projection display apparatus according to  claim 19 , wherein the projection optical section causes the illuminator to output the illumination light toward the first surface of the polarization separation device, the light valve to modulate the first polarized component, out of the illumination light, that has been outputted from the second surface of the polarization separation device, and output light resulting from the modulation toward the second surface of the polarization separation device, and the projection lens to project, toward the projection surface, light, out of the light resulting from the modulation, that has been outputted from the fourth surface of the polarization separation device.
