摘要： This invention provides a projector capable of effectively utilizing the light from the light source and significantly reducing the light illuminating the outside of the area to be illuminated, thereby attaining an excellent efficiency of light utilization. In the illuminating system of the present invention provided with a light source and a reflector, there is further provided a circular reflector of a spherical surface, for returning the light, which emerges from the light source to the outside of the area to be illuminated, without being reflected on the reflector, to the light source. Also there is provided a flat mirror or a substantially spherical sub reflector for returning the light, which proceeds to the outside of the area to be illuminated, after being reflected on the reflector, to the light source. The sub reflector may be provided in the vicinity of the light source.

摘要： An optical modulating device comprises a polarizer, an analyzer and liquid crystals positioned between the polarizer and the analyzer. The device controls the birefringence of the liquid crystals by applying an electric field to the liquid crystals so as to change the polarization of light of the device. The device further comprises a rotatable halfwave plate which is positioned between the liquid crystals and the analyzer or between the liquid crystals and the polarizer in such a manner that the optical axis of the halfwave plate will be rotated around the optical axis of light coming into the optical modulating device. The device varies the rotational angle of the halfwave plate in accordance with the temperature of the liquid crystals or the environment thereof.
