Patent Images
1. A head mounted display with a see-through view of the surrounding environment with an overlaid displayed image comprising:
- a. upper optics with a first optical axis including;
i. an emissive image source that provides image light comprised of one or more narrow spectral bands of light;
ii. one or more lenses; and
iii. a stray light trap positioned to prevent a substantial portion of stray scene light from the surrounding environment from entering the upper optics; and
b. lower optics with a second optical axis including;
i. a planar beam splitter angled relative to the first and second optical axes; and
ii. a curved partially reflective mirror, wherein a substantial portion of the image light reflects off of the curved partially reflective mirror and is then transmitted through the planar beam splitter.
