Patent
High contrast illumination system for video projector
TL;DR: In this paper, a high contrast illumination system was proposed for use with light valves that have an array of reflective pivotable pixels and an asymmetric aperture is disposed in the light path with its longitudinal axis located along the pivot axis of the pixels.

Display system with equal path lengths
Thomas Stewart Mckechnie,Jill Forer Goldenberg,Joshua Daniel Eskin,Jeffrey A. Shimizu,Ralph Bradley,William F. Guerinot +5 more
TL;DR: In this article, the authors describe various ways of arranging the light valves, as well as providing illumination, to enable optimum illumination of each of the light valve, and present a variety of configurations of the liquid crystal displays.
Patent
Luminaire having a reflector for mixing light from a multi-color array of leds
TL;DR: In this paper, a light source includes an array of LEDs in each of a plurality colors such as red, green, and blue in the entrance aperture of a tubular reflector which preferably has convex walls facing the optic axis and flares outward toward the exit aperture, and preferably has a polygonal cross section such as a square.
Patent
Image display system
TL;DR: In this article, non-absorptive polarization components were used to polarize light illuminating an imaging device, reducing cost and cooling requirements, increasing durability, and permitting the use of high powered light sources.
Patent
Color projection system employing reflective display devices and prism illuminators
TL;DR: In this article, a color projection display system employing display devices operating in the reflective mode is described. But the optical path lengths are considerably reduced by employing prism illuminators immediately adjacent the display devices to illuminate the reflective display surface and to spatially separate the incident and reflected illumination.
