摘要： A transmitter that outputs an image signal for displaying a first image and outputs an image signal of a synthesized image made of the reversal image of the first image and a second image. A display apparatus, based on the image signals output from the transmitter, displays the first image and the synthesized image with circular polarizations having different senses of rotation from each other. A receiver includes a circular polarization selecting and transmitting means that separates the first image and the synthesized image displayed on the display apparatus, based on the sense of rotation of the circular polarization, and selectively allows the images to pass therethrough, so as to be able to photograph the first image displayed on the display apparatus.

摘要： An optical switch includes electro-optic crystal, and electrode unit including a plurality of electrodes arranged on the same plane in electro-optic crystal to extend in parallel to one another. A refractive index of a part of electro-optic crystal is changed by an electric field generated at electrode unit, thereby switching transmission and reflection of light incident on electro-optic crystal. Electro-optic crystal has an entrance surface through which light enters and an exit surface from which light exits. Electrode unit is located between the entrance surface and the exit surface. An angle θx formed between a longitudinal direction of electrodes and at least one surface from among the entrance surface and the exit surface is set near an angle that satisfies the expression θx=90°−Sin−1[ cos(Tan−1(n))] in a wavelength of light to be modulated.

摘要： A planar light source, Fresnel lens sheet, and louver are disposed in the stated order in a light source apparatus. The Fresnel lens sheet deflects and focuses in one dimension light that has entered from the planar light source. The louver is disposed in the optical path of the light emitted from the Fresnel lens sheet, and the directivity of the light can be increased by restricting the traveling direction of the light to the focal direction of the Fresnel lens sheet. The light utilization ratio can thereby be increased, the directivity of planarly emitted light can be increased, and the brightness can be made uniform at the point of observation.
