Abstract

According to one embodiment, an optical instrument includes a hand-held housing that houses multiple optical devices and an eyepiece. The optical devices are configured to generate a corresponding multiple number of images on the eyepiece such that each image is contiguously aligned with one another along their sides to form a panoramic image on the eyepiece.

Claims

1. An optical instrument comprising:

a hand-held housing;

three video cameras configured in the hand-held housing that are operable to generate three images on an eyepiece configured in the housing, each image contiguously aligned with one another along their sides to form a panoramic image on the eyepiece;

a first movable mirror operable to selectively reflect light from an objective lens to one of the three video cameras while in a first position and allow light from the objective lens to proceed to the eyepiece while in a second position, the one camera centrally disposed between the two other video cameras;

a second movable mirror operable to reflect light from a display to the eyepiece while in the first position and allow light to proceed from the objective lens to the eyepiece while in the second position.

an image intensifying device optically coupled to an objective lens through a third movable mirror, the movable mirror operable to reflect light from the objective lens to the image intensifying device while in a third position and allow light to pass from the objective lens to the one video camera while in a fourth position.

2. An optical instrument comprising:

a hand-held housing; and

a plurality of optical devices configured in the hand-held housing that are operable to generate a corresponding plurality of images on an eyepiece configured in the housing, each image contiguously aligned with one another along their sides to form a panoramic image on the eyepiece.

3. The optical instrument of claim 2, wherein the plurality of optical devices comprises a plurality of video cameras and the plurality of images comprises a plurality of video images generated by the plurality of cameras.

4. The optical instrument of claim 2, further comprising an objective lens and a movable mirror optically coupled to an image intensifying device and one of the plurality of optical devices, the movable mirror operable to reflect light from the objective lens to the image intensifying device while in a first position and allow light from the objective lens to proceed to the one optical device while in a second position.

5. The optical instrument of claim 4, wherein the image intensifying device comprises a night vision camera.

6. The optical instrument of claim 2, further comprising an objective lens optically coupled to one of the plurality of optical devices through a first movable mirror and a display optically coupled to the eyepiece through a second movable mirror, the one optical device comprising a video camera operable to generate an electrical signal representative of one image that is displayed on the display, the first movable mirror operable to reflect light from the objective lens to the video camera while in a first position and allow light from the objective lens to proceed to the eyepiece while in a second position, the second movable mirror operable to reflect light from a display to the eyepiece while in the first position and allow light from the objective lens to proceed to the eyepiece while in the second position.

7. The optical instrument of claim 2, wherein the plurality of optical devices comprises a first optical device and two second optical devices, the first optical device configured to generate its associated image in between the images generated by the two second optical devices, the first optical device comprising an adjustable field-of-view.

8. The optical instrument of claim 2, wherein the plurality of optical devices comprises three optical devices configured to generate three images, each image having a lateral field-of-view of at least 45 degrees, the panoramic image having at least a 120 degree field-of-view.

9. The optical instrument of claim 2, further comprising an image processing unit coupled to an eye tracker camera, the eye tracker camera optically coupled to the eyepiece, the image processing unit operable to:

receive a signal from the eye tracker camera indicative of the orientation of an eye viewing the eyepiece;

associate the signal with one or more elements in the image generated by one of the optical devices; and

generate a marker element on the eyepiece proximate the one or more elements.

10. A method comprising:

generating, on an eyepiece, a plurality of images using a plurality of optical devices configured in a hand-held housing that houses the eyepiece; and

contiguously aligning each of the plurality of images with one another along their sides to form a panoramic image on the eyepiece.

11. The method of claim 10, wherein generating the plurality of images using the plurality of optical devices comprises generating a plurality of video images using a plurality of video cameras.

12. The method of claim 10, further comprising:

alternatively reflecting light, using a movable mirror, between a night vision camera that generates one of the plurality of images and a video camera that generates the one image; and

displaying the one image on the eyepiece.

13. The method of claim 12, wherein reflecting light to an image intensifying device comprises reflecting light to a night vision camera.

14. The method of claim 10, further comprising

alternatively reflecting incoming light, using a first movable mirror, between one of the plurality of optical devices and the eyepiece, the one optical device comprising a video camera, the incoming light received through an objective lens;

and

alternatively reflecting a second light, using a second movable mirror, from a display or the objective lens to the eyepiece.

15. The method of claim 10, wherein contiguously aligning each of the plurality of images with one another comprises contiguously aligning two second images of the plurality of images on either side of a first image of the plurality of images, and adjusting a field-of-view of the first image.

16. The method of claim 10, wherein generating the plurality of images using a plurality of optical devices comprises generating three images that each have a lateral field-of-view of at least 45 degrees, the panoramic image having at least a 120 degree field-of-view.

17. The method of claim 10, further comprising:

receiving a signal from an eye tracker camera indicative of the orientation of an eye viewing the eyepiece;

associating the received signal with one or more elements in the image generated by one of the optical devices; and

generating a marker element on the eyepiece proximate the one or more elements.
