Using a single spatial light modulator for stereoscopic images of high color quality and resolution

Abstract

Since stereoscopy is a fundamental part of an immersive display, stereoscopic imaging has been part of many research papers and patents in the past. There have been different approaches developed to generate and transport the two images to the human eye. In general we can say that image generation may be done by one or two units and image encoding is done either by frequency, time or orientation. For image generation Projectors of CRT, LCD, LCOS and DLP Type are well known. Since 3D has gained more public interest, in the past different approaches have been undertaken to simplify setups for stereoscopy. Often two projectors are used to generate stereoscopic images. But these need more maintenance than a single projector system. For a single projector, frame interleaved stereoscopic Image generation is well known for 3Chip DLP Systems using three spatial light modulators to generate the image. In this paper we describe a solution producing frame interleaved output using a single chip spatial light modulator or digital micro mirror device (DMD) allowing combining high resolution and coloring quality.
