Embodiment Construction

[0016] Throughout the following description, specific details are set forth in order to provide a thorough understanding to those skilled in the art. However, well known elements may not have been shown or described in detail to avoid unnecessarily obscuring the disclosure. Accordingly, the description and drawings should be regarded in an illustrative rather than a restrictive sense.

[0017] As used herein, the terms "component," "system," "interface," "controller," etc., are intended to refer to a computer-related entity, which may be hardware, software (eg, in execution), and / or firmware. For example, any of these terms may be a process running on a processor, a processor, an object, an executable, a program and / or a computer. As an illustration, both an application running on a server and the server can be a component and / or a controller. One or more components / controllers can reside within a process and a component / controller can be localized on one computer and / or dis...

Abstract

An Acoustic-Optic A / O device receives light from a source and deflecting the light onto the second A / O device which may be a multi-stacked set of individual A / O devices. The first and second devices may deflected light according to control signals. Also, a multi-modulator projector display system including a light source, controller, an A / O modulator illuminated by the light source and capable of deflecting light according to controller signals, a second modulator illuminated by light from said A / O modulator and capable of modulating the A / O modulated light, said second modulator comprising a plurality of mirrors, and said second modulator capable of modulating the light according to controller signals.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Patent Application No. 61 / 914,045, filed December 10, 2013, the entire contents of which are hereby incorporated by reference. technical field [0003] The present invention relates to projector display systems, and more particularly, to modulators for dual or multi-level modulation projection display systems. Background technique [0004] In a conventional projector system, there is usually a single light source that illuminates the screen with an image modulated by some optical system within the projector. When there are "highlights" (i.e., areas of high brightness - for example, specular reflections of surfaces in an image, direct sunlight, shiny objects, one area substantially brighter than other areas, etc.) to be projected When displaying an image, this bright portion will have the same brightness level as the "full" screen. In this case, the light emitted by t...
