Abstract

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

Claims

1. A method for providing adjustment of the alignment of an image displayed by a display assembly in a head mounted comprising:

a light source providing light;

a reflective image source;

a partially reflective layer that redirects light from the light source to uniformly illuminate the reflective image source plus an adjacent space;

reflecting the light off of the reflective image source to provide image light to display optics;

manipulating the image light in display optics to provide an image to a user; and

adjusting the alignment of the image provided to the user by moving the reflective image source within the adjacent space

wherein a mask is provided to substantially cover the adjacent space.

2. The method of claim 1 wherein the mask is stiff and it slides under an adjacent structure when moved.

3. The method of claim 1 wherein the mask is flexible.

4. The method of claim 1 wherein the adjustment includes lateral movements and rotational movements.

5. The method of claim 1 wherein the mask covers the edges of the reflective image source.

6. The method of claim 1 wherein the mask is black.
