摘要

Aspects of the present invention relate to providing see-through computer display optics.

主权项

1. A compact optics module for a head mounted display including a DLP image source comprising:
a. a polarized light source providing illumination light; b. a flat reflective polarizer to reflect the illumination light toward the DLP image source and transmit image light, wherein the illumination light is provided at an angle to the DLP; c. a quarter wave retarder to change the polarization state of the illumination light as it is reflected by the DLP image source thereby providing image light; d. at least one light trap to absorb a portion of off-state image light; e. a lens element to provide a viewable field of view of on-state image light in image displayed by the DLP image source; and f. a combiner to reflect the on-state image light toward a user's eye and provide a see-through view of a surrounding environment.
