Appl. No.:

09/568965

Inventors:

Barney J. Kaelin - Playa del Rey CA
Stephen J. Reinsch - Escondido CA

Assignee:

Victor Company of Japan, Limited

International Classification:

G03B 2100

US Classification:

353 31, 353 33, 353 34, 353 37, 353122, 349 25, 349 61, 345 16, 345 32, 345135

Abstract:

An image projection system is provided for generating an energy efficient output representative of a desired input image. The image projection system includes a light source positioning device for directing the light from a light source onto a spatial light modulator. An image source provides the desired image to the spatial light modulator and also image information to a light source position controller for coordinating the light source positioning device, such that the light from the light source impinges substantially only the area of the spatial light modulator which contains the desired image. In particular, the controller actuates the light source positioning device by using a predefined scan that corresponds to the desired image. The spatial light modulator modulates the light with the desired input image and generates an output representative of the desired image. A beam brush may also be used for changing the width of the projection beam from light source, thereby improving image resolution and maximizing energy conservation.

7/305852

Inventors:

Barney Kaelin - Playa del Rey CA

International Classification:

G03B 2156

US Classification:

353 10

Abstract:

A device for 3-dimensional imaging of laser light effects when said light is imaged on and passes through plural imaging elements resulting in a multi-planer and apparently 3-dimensional image when viewed.
