主权项

1. A compact optics module for a head mounted display including a DLP image source comprising:
a. a light source that provides illumination light directly onto the DLP image source; b. the DLP image source providing reflected image light comprised of on-state light and off-state light; c. at least one light trap at the side of the optics module to absorb the off-state light; d. a field lens provided at a distance from the DLP image source that is sufficient for direct illumination; e. a power lens to provide a viewable field of view comprised of the image light; f. a fold mirror to reflect the on-state light provided by the DLP image source toward the power lens; and g. a combiner to reflect on-state light toward a user's eye to provide a displayed image and simultaneously provide a see-through view of a surrounding environment.
