Patent Images
1. A head-worn computer, comprising:
- a. A see-through optical system adapted to visually present digital content to an eye of a person wearing the head-worn computer, wherein the person can see a surrounding environment through the see-through optical assembly, the see-through optical system further comprising;
i. An image source adapted to generate display light based on the digital content; and
ii. A partially reflective combiner adapted to provide at least the following;
1. Reflecting at least a first portion of the display light toward the user'"'"'s eye such the person perceives the digital content as an image;
2. Transmitting at least a second portion of the display light toward a light trap;
3. Reflecting at least a first portion of light received from the surrounding environment toward a camera; and
,4. Transmitting a portion of the light received from the surrounding environment toward the user'"'"'s eye to provide the see-through view of the surrounding environment.

Abstract
Aspects of the present invention relate to methods and systems for providing a high transmission see-through view of the environment while trapping escaping light from the display system. In embodiments, a camera system is also provided that is aligned with the display system to provide images of the environment in a viewing direction of the user.

11. A head-worn computer, comprising:
a. A see-through optical system adapted to visually present digital content to an eye of a person wearing the head-worn computer, wherein the person can see a surrounding environment through the see-through optical assembly, the see through optical system further comprising; i. A partially reflective combiner adapted to reflect, towards the eye, display light based on the digital content; and ii. A camera positioned to capture light from the surrounding environment that is reflected off a surface of the partially reflective combiner, wherein the surface is coaxially aligned with a forward facing position of the eye.

12. A head-worn computer, comprising:
a. A see-through optical system adapted to visually present digital content to an eye of a person wearing the head-worn computer, wherein the person can see a surrounding environment through the see-through optical assembly, the see through optical system further comprising; i. A partially reflective combiner adapted to reflect, towards the eye, display light based on the digital content, wherein the partially reflective combiner is in-line with an optical axis that provides the eye with the see through view of the surrounding environment; and ii. Wherein the partially reflective combiner includes an electronically controllable surface to regulate a see through transparency percentage of the partially reflective combiner.
