摘要： A first linearly polarized bundle of rays of incident rays is converted by optical modulation with an input video signal into a second linearly polarized bundle of rays orthogonal to the first rays in polarization. The first rays pass through a polarizer before optically modulated. A second linearly polarized bundle of rays originally involved in the incident rays is reflected by the polarizer in a first direction. The second rays obtained by the optical modulation are reflected by the polarizer in a second direction. The second rays reflected in the second direction pass through another polarizer. A first linearly polarized bundle of rays involved in the reflected second rays is reflected by the other polarizer. The reflected first rays is detected by an optical sensor that is positioned outside an optical path of the second rays originally involved in the incident rays and reflected in the first direction.

摘要： There are arranged two light sources 21a, 21b, a triangular prism mirror 22 for synthesizing lights emitted from the two light sources 21a, 21b and a first dichroic mirror 41 for optically separating the synthesized lights, in this order. The flux of light synthesized by the triangular prism mirror 22 has a long axis in a photosynthetic direction of the lights. The long axis direction of flux intersects with a spectroscopic direction of the first dichroic mirror 41 at a right angle.

摘要： To provide a wire grid polarizer used in an image display apparatus, in which even when the image display apparatus is of a small compact structure and provides high output of power from the light source, shape transformation of the glass substrate occurring due to generation of heat caused by light absorption in the wire grid is prevented and in which by efficient usage of light rays from the light source, high-quality images can be displayed by the image display device and power consumption is low. A wire grid 2 formed of metal in a fine comb shape is formed on a glass substrate 1 and antireflection coatings 3a and 3b are disposed respectively on the front surface part and the rear surface part of the wire grid 2 of the glass substrate 1.
