EYEPIECE FOR NEAR-TO-EYE DISPLAY WITH MULTI-REFLECTORS |
摘要 |
<p>An eyepiece for a head mounted display includes an illumination module, an end reflector, a viewing region, and a polarization rotator. The illumination module includes an image source for launching computer generated image ("CGI") light along a forward propagating path. The end reflector is disposed at an opposite end of the eyepiece from the illumination module to reflect the CGI back along a reverse propagation path. The viewing region is disposed between the illumination module and the end reflector. The viewing region includes a polarizing beam splitter ("PBS) and non-polarizing beam splitter ("non-PBS") disposed between the PBS and the end reflector. The viewing region redirects the CGI light from the reverse propagation path out of an eye-ward side of the eyepiece. The polarization rotator is disposed in the forward and reverse propagation paths of the CGI light between the viewing region and the end reflector.</p> |
