Abstract

A system, method, and helmet includes a collection optic configured to collect light from a scene and create an image; a fiber optic bundle configured to receive the image from the collection optic; an opaque ballistic face shield configured adjacent to the fiber optic bundle; and a projection optic configured to receive the image from the fiber optic bundle and project the image to a viewer. The collection optic includes a field of view (FOV) of greater than 30 degrees, and preferably greater than 50 degrees. The collection optic images the collected light gathered from the scene onto an end of the fiber optic bundle. The fiber optic bundle goes through or around the opaque ballistic face shield. The opaque ballistic face shield is non-electric and includes silicon carbide and polyethylene. In one embodiment, the opaque ballistic face shield includes at least two pounds of silicon carbide and polyethylene.

First claim

What is claimed is:

1. A system comprising:
a collection optic configured to collect light from a scene and create an image;
a fiber optic bundle configured to receive said image from said collection optic;
an opaque ballistic face shield configured adjacent to said fiber optic bundle; and
a projection optic configured to receive said image from said fiber optic bundle and project said image to a viewer.

2. The system of claim 1 , wherein said collection optic comprises a field of view (FOV) of greater than 30 degrees.

3. The system of claim 1 , wherein said collection optic comprises a field of view (FOV) of greater than 50 degrees.

4. The system of claim 1 , wherein said collection optic images said collected light gathered from said scene onto an end of said fiber optic bundle.

5. The system of claim 1 , wherein said fiber optic bundle goes through said opaque ballistic face shield.

6. The system of claim 1 , wherein said fiber optic bundle goes around said opaque ballistic face shield.

7. The system of claim 1 , wherein said opaque ballistic face shield is non-electric.

8. The system of claim 1 , wherein said opaque ballistic face shield comprises silicon carbide and polyethylene.

9. The system of claim 1 , wherein said opaque ballistic face shield comprises at least two pounds of silicon carbide and polyethylene.

10. A helmet comprising:
a collection optic configured to collect light from a scene and create an image;
a non-electric opaque ballistic face shield adjacent to said collection optic, wherein said opaque ballistic face shield comprises silicon carbide and polyethylene;
a fiber optic bundle configured to receive said image from said collection optic; and
a projection optic configured to receive said image from said fiber optic bundle and project said image to a viewer.

11. The helmet of claim 10 , wherein said collection optic comprises a field of view (FOV) of greater than 30 degrees.

12. The helmet of claim 10 , wherein said collection optic comprises a field of view (FOV) of greater than 50 degrees.

13. The helmet of claim 10 , wherein said collection optic images said collected light gathered from said scene onto an end of said fiber optic bundle.

14. The helmet of claim 10 , wherein said fiber optic bundle goes through said opaque ballistic face shield.

15. The helmet of claim 10 , wherein said fiber optic bundle goes around said opaque ballistic face shield.

16. The helmet of claim 10 , wherein said opaque ballistic face shield comprises at least two pounds of silicon carbide and polyethylene.

17. A method for collecting and transferring an image, said method comprising:
collecting light from a scene and creating an image using a collection optic;
receiving said image from said collection optic using a fiber optic bundle;
providing an opaque ballistic face shield adjacent to said fiber optic bundle; and
receiving said image from said fiber optic bundle and projecting said image to a viewer using a projection optic.

18. The method of claim 17 , wherein said collection optic comprises a field of view (FOV) of greater than 30 degrees.

19. The method of claim 17 , further comprising using said collection optic to image said collected light gathered from said scene onto an end of said fiber optic bundle.

20. The method of claim 17 , wherein said opaque ballistic face shield is non-electric and comprises at least two pounds of silicon carbide and polyethylene.
