Abstract

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

First claim

We claim:

1 . A head-worn computer, comprising:
a. an image source positioned within the head-worn computer such that an image from the image source is projected towards a combiner; b. the combiner being an optical element that is at least partially see-through and at least partially reflective such that light from a surrounding environment passes through the combiner to an eye of a user wearing the head-worn computer and the image is reflected to the eye of the user; and the combiner removably and replaceably attached to a frame of the head-worn computer.

2 . The head-worn computer of claim 1 , wherein the combiner is magnetically attached to the frame.

3 . The head-worn computer of claim 1 , wherein the combiner is aligned within the frame with pins such that placement of the combiner is repeatable.

4 . The head-worn computer of claim 1 , wherein the combiner is adapted to reflect the image directly towards the eye without additional intermediate reflection.

5 . The head-worn computer of claim 1 , wherein the combiner is one of a plurality of types of combiners and the removability offers the user choice in combiner type.

6 . The head-worn computer of claim 5 , wherein the type is polarized.

7 . The head-worn computer of claim 5 , wherein the type includes a notch mirror.

8 . The head-worn computer of claim 5 , wherein the type is of a particular level of tint.

9 . The head-worn computer of claim 5 , wherein the type is a partial mirror.

10 . The head-worn computer of claim 5 , wherein the type is adapted to block faceglow.

11 . The head-worn computer of claim 1 , wherein the image source is a reflective image source.

12 . The head-worn computer of claim 1 , wherein the image source is an emissive image source.

13 . The head-worn computer of claim 1 , further comprising an eye imaging camera, wherein the eye imaging camera is positioned to capture an image of the eye after being reflected off of the combiner.

14 . The head-worn computer of claim 13 , wherein the eye imaging camera is positioned in the frame adjacent to the combiner.

15 . The head-worn computer of claim 13 , wherein the eye imaging camera is positioned in an upper optical module to capture the image of the eye in an optical path substantially perpendicular to the front of the eye of the user.
