Wearable optical display system for unobstructed viewing

1. An optical display system configured for attachment to a user wearable optical device, the user wearable optical device includes a user attachment section, and a partially transmissive partially reflective lens that is coupled with the user attachment section, the user attachment section is configured for detachably mounting the user wearable optical device to a head of a user, the partially transmissive partially reflective lens is configured to be facing at least one eye of the user, the optical display system comprising:

an electro-optical unit comprising:

a processor; and

a light projection unit coupled with said processor, said light projection unit is configured to transmit light beams onto said partially transmissive partially reflective lens, said light projection unit is configured to be located at a glabellar region of said user; and

at least one coupler that is configured to couple said electro-optical unit with at least one of said user attachment section and said partially transmissive partially reflective lens, wherein said electro-optical unit is configured to be positioned with respect to said user attachment section such that when said user wearable optical device is mounted on said user, said electro-optical unit is located at the glabellar region of said user, thereby providing a substantially unobstructed field of regard (FOR) to said user.

2. The optical display system according to claim 1 , wherein said at least one coupler employs a coupling method selected from a list consisting of:

mechanical coupling;

chemical coupling;

thermal coupling; and

magnetic coupling.

3. The optical display system according to claim 1 , wherein said user attachment section is attachable to, and detachable from said optical display system.

4. An optical display system configured for attachment to a user wearable optical device, the user wearable optical device includes a user attachment section that is configured for detachably mounting the user wearable optical device to a head of a user, the optical display system comprising:

an electro-optical unit comprising:

a processor; and

a light projection unit coupled with said processor, said light projection unit is configured to transmit light beams onto said partially transmissive partially reflective lens, said light projection unit is configured to be located at a glabellar region of said user;

a partially transmissive partially reflective lens that is coupled with said electro-optical unit, said partially transmissive partially reflective lens is configured to be facing at least one eye of said user; and

at least one coupler that is configured to couple said electro-optical unit and said partially transmissive partially reflective lens with said user attachment section, wherein said electro-optical unit is configured to be positioned with respect to said user attachment section such that when said user wearable optical display system is mounted on said user, said electro-optical unit is located at the glabellar region of said user, thereby providing a substantially unobstructed field of regard (FOR) to said user.

5. The optical display system according to claim 4 , wherein said user attachment section is coupled with either one of a body and a housing of said electro-optical unit, via at least one attachment feature.

6. The optical display system according to claim 4 wherein said electro-optical unit is attachable to and detachable from said user attachable section and said partially transmissive partially reflective lens.

7. The optical display system according to claim 4 , further comprising a nosepiece that is attachable to, and detachable from either one of said partially transmissive partially reflective lens, and said electro-optical unit.
