Abstract

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

Claims

1. A wearable head device, comprising:

a frame having a first portion configured to be positioned a first distance from a head of a user of the wearable head device and a second portion configured to be positioned a second distance from the head;

a plurality of optical modules housed in the frame, wherein each optical module of the plurality of optical modules is configured to adjust to a facial geometry of the user;

a first electronics board disposed adjacent to the first portion of the frame and between two optical modules of the plurality of optical modules;

a second electronics board disposed adjacent to the second portion of the frame and between the two optical modules of the plurality of optical modules, the second electronics board comprising a processor; and

a heat sink disposed between the two optical modules of the plurality of optical modules, the heat sink thermally coupled to the processor.

2. The wearable head device of claim 1, further comprising:

a lower optical surface; and

a multiply folded optical element configured to provide light to the lower optical surface, wherein;

the lower optical surface is adapted to receive image light associated with a displayed image from a multiply folded optical path,

the lower optical surface is further adapted to reflect at least a portion of the received image light towards an eye of the user, and

the lower optical surface and the plurality of see-through optical elements are configured to transmit a portion of ambient light from a surrounding environment of the user to simultaneously provide a see-through view of the user'"'"'s surrounding environment and a view of the displayed image.

3. The wearable head device of claim 2, wherein the multiply folded optical element comprises at least two substantially planar reflective surfaces, wherein:

each reflective surface is rotated along an optical axis of the respective reflective surface and with respect to another reflective surface, and

the reflective surfaces and multiply folded optical element are configured to align an image provided to the eye of the user of the wearable head device by the plurality of see-through optical modules.

4. The wearable head device of claim 1, further comprising:

a plurality of progressively tinted lenses, wherein;

each lens in the plurality of progressively tinted lenses comprises a respective first portion associated with low transmissivity, the first portion disposed in front of a portion of an upper optical module with respect to the head of the user, and

each lens in the plurality of progressively tinted lenses comprises a respective second portion associated with high transmissivity, the second portions of each lens disposed in front of a lower optical module and

the plurality of progressively tinted lenses is configured to at least partially conceal the upper optical module behind the respective second portions to provide a see-through view of a surrounding environment.

5. The wearable head device of claim 4, wherein each respective first portion of each lens in the plurality of progressively tinted lenses is disposed in front of one or more of the first electronics board and the second electronics board with respect to the head of the user, and each respective second portion of each lens in the plurality of progressively tinted lenses is disposed in front of one or more of the first electronics board and the second electronics board with respect to the head of the user.
