See-through computer display systems
First Claim
Patent Images
1. A see-through head mounted display with controllable light blocking comprising:
- a. an optics module that provides polarized image light in correspondence to a displayed image;
b. a flat combiner to reflect the image light while simultaneously transmitting more than 50% of incident unpolarized light from the environment, along an optical axis that proceeds to the user'"'"'s eye to provide a view of the displayed image overlaid onto a see-through view of the environment; and
c. a controllable light blocker positioned adjacent to the flat combiner that controllably blocks light from the environment so it is not incident on the combiner.
