See-through computer display systems

摘要

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

主权项

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.
