Publication number: 20140368797Abstract: An image projection system (300, 400) uses a polarized illumination source (306) in conjunction with a linear polarizer (314) located before and a quarter-wave retarder (312) located after an imager field lens 118 along a projection optical axis (216) between a spatial light modulator reflective imager (120) and a projection lens (122). The combination serves to block illumination light (210a) reflected off the imager field lens (314) and other optics (408, 411), while passing illumination light (210c) modulated by ON-state reflector elements of the reflective imager 120. The reduction of ghost reflections and stray light improves dark state (OFF-state reflector element) contrast.Type: ApplicationFiled: June 26, 2013Publication date: December 18, 2014Inventors: John M.

Patent number: 8075140Abstract: A light engine has a light source front surface that emits non-collimated light. A collection lens collects the non-collimated light and provides incompletely collimated light. A collimating lens receives the incompletely collimated light and provides a collimated image. A non-orthogonal polarizing filter receives the collimated image and passes a polarized portion of the collimated image as a direct component of the polarized light engine image. The non-orthogonal polarizing filter reflects a recycled image back to the front surface. The non-orthogonal shape of the polarizing filter is selected according to the pattern of light on the light source front surface.Type: GrantFiled: July 2, 2007Date of Patent: December 13, 2011Assignee: 3M Innovative Properties CompanyInventors: William E.

Patent number: 7959305Abstract: A digital micromirror projection display system is disclosed in which “off” pixel light is recaptured and recycled. In the disclosed system, a digital micromirror device directs incident light for “on” pixels in the image to be displayed through projection lenses to a projection screen. The digital micromirror device directs incident light for “off” pixels back toward the light source for recapture by a light integrator. Both the incident and projected light can pass through a rear group of projection lenses, with the first projection lens being disposed near the digital micromirror device. A mirror directs the incident light toward the digital micromirror device, and the “off” pixel light from the digital micromirror device toward the light integrator. As a result, “off” pixel light can be recycled without degrading image contrast, in a manner that can place fast projection lenses close to the digital micromirror device to save cost.Type: GrantFiled: August 30, 2007Date of Patent: June 14, 2011Assignee: Texas Instruments IncorporatedInventor: Patrick R.
