A projector to be simple and capable of being miniaturized. White light is decomposed by a color decomposition/composition device into red light, green light, and blue light, which are incident to a first, second, and third mirror deflection type light modulators and first effective reflected light to third effective reflected light obtained by the first, second, and third mirror deflection type light modulators are composed together, so that color decomposition/composition can be performed by t...

A projector suitable for a rear projection type receiver is disclosed. The projector has a device for generating an image and an image projecting device for projecting the image to a screen. The image projecting device includes a projection lens system and a reflector. The projection lens system directs the light flux indicative of the image from the image generating device toward the reflector so as to be away from the screen. The reflector bends the light flux and directs the light flux from t...

A projecting apparatus having a first projecting system for projecting an object to be projected to form an intermediate image, and a second projecting system for projecting the intermediate image formed by the first projecting system onto a screen. The first projecting system is adapted to distort the image of the object, and the second projecting system is adapted to correct the distorted image to project an enlarged image analogous to the object onto the screen.

A liquid crystal type video projector is disclosed which has a reflection type optical modulator for effective use of beams from a radiation source such as a lamp or the like. The projector further comprises means for modulating the plane of polarization of a polarized beam entering the radiation source and for reflecting the polarized beam, thereby causing a reflection beam and an optical arrangement. The optical arrangement includes a first polarizing beam splitter for separating the beam from...

The first projecting system is adapted to distort the image of the object, and the second projecting system is adapted to correct the distorted image to project an enlarged image analogous to the object onto the screen.

A projector is provided with an illuminator, dichroic mirror for splitting illumination light into a plurality of light components, a plurality of light propagating paths in which the plurality of light components are introduced to corresponding image panels. In a propagating path having a largest distance, there are provided a relay optical system having a relay lens and a field lens. The relay lens and/or the field lens have a refractive index of 1.75 or more.

A projector comprises a substantially horizontal table, a substantially centrally above the table arranged projection optics (2), a light source (3) which is located above the table and arranged to illuminate the table, a deflexion mirror (4) for substantially horizontal deflexion of a light radiating vertically upwardly from the table, and a light shaft (5) which at least partially screens off the area between the optics (2) and the table (1) from the surroundings and is characterized in that a...

In a projection display apparatus, an air inlet is formed below an optical modulation device and a color synthesizing system, and a suction fan is placed across the optical modulation device and the color synthesizing system. Thereby the optical modulation device and the color synthesizing system are uniformly cooled by air on the suction side of the suction fan. A structure fixing the optical modulation device and the color synthesizing system is provided with a suction opening cooling the opti...

A projection-type display apparatus in accordance with the invention reduces the margin formed around the image forming range of the light valves, and forms a bright projected image. Emitted light from a light source lamp unit of a projection-type display apparatus illuminates liquid crystal light valves of each color via an integrator optical system. First and second lens plates of an integrator optical system that serves as a uniform illuminating optical system are disposed such that the attac...

A projection-type display apparatus includes a light source, a uniform illumination optical system, a color separating system for separating a white light beam emitted from the uniform illumination optical system into three color beams, three liquid crystal panels for respectively modulating each of the separated color beams, a light guide system located on an optical path of the color beam having the longest optical path among the separated color beams, a dichroic prism for synthesizing the bea...
