Abstract:
A projection display unit includes a projection optical system, a polarization separation device, and a detection optical system. The projection optical system includes an illuminator, a projection lens, and a light valve. The light valve modulates illumination light supplied from the illuminator on a basis of an image signal, and outputs the modulated illumination light toward the projection lens. The polarization separation device 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. The imaging device is disposed in a position that is optically conjugate to a position of the light valve, and receives, via the projection lens and the polarization separation device, light based on invisible light applied along a plane in vicinity of the projection surface. The following conditional expression (1): d1<β×d2 is satisfied.

Claim (Index 6):
The projection display unit according to  claim 5 , wherein\n the imaging device receives part of light, out of the invisible light, that is reflected by an object, and the image circle has a radius that satisfies the following conditional expression,\n R 1\u2265 R 0+ h /\u03b1\u00d7tan \u03b8min\u2003\u2003(2) \n where R1 is the radius of the image circle of the projection lens, R0 is a radius of a circle that is in contact with a pair of vertices of the effective region of the light valve, \u201ch\u201d is a height, from the projection surface, of the plane along which the invisible light is to be applied, \u03b1 is a projection magnification, and \u03b8min is a minimum value of an angle formed by the projection surface and the part of the reflected light entering the detection optical system.
