Abstract
Aspects of the present invention relate to providing see-through computer display optics.
Claims34
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.

- a. an optics module that provides image light in correspondence to a displayed image;
- b. a flat combiner comprising a notch mirror to reflect the image light while simultaneously transmitting more than 50% of incident 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.
