Abstract

Optical system ( 10 ) for imaging an object includes at least: a loupe ( 12 ) including a lens ( 16 ) for magnifying the object, the lens being disposed in a frame; and a camera ( 14 ) arranged between the lens ( 16 ) of the loupe ( 12 ) and the object to image at least a portion of the same field of view as the lens ( 16 ) of the loupe ( 12 ).

First claim

The invention claimed is:

1. An optical system for imaging an object comprising at least:
a loupe comprising a lens for magnifying the object, the lens being disposed in a frame;
a camera arranged between the lens of the loupe and the object to image at least a portion of the same field of view as the lens of the loupe;
a handle extending from the frame, wherein the camera:
is movable between a retracted position in the handle and an extended position, and
is spaced away from the handle in the extended position to image at least a portion of the same field of view as the lens of the loupe; and

a transparent digital display disposed on the lens and is arranged for displaying in real time pictures and/or videos imaging by said camera when the camera is in the extended position and for being transparent when the camera is in the retracted position.

2. The optical system according to claim 1 , wherein the camera is slideably mounted in the handle.

3. The optical system according to claim 1 , wherein the handle further houses a telescopic pod pivotally movable between a retracted position in the handle and an extended position wherein the telescopic pod is spaced away from the handle and arranged to position the camera at a distance from the object to obtain a same field of view seen by an eye of a user directly through the lens.

4. The optical system according to claim 1 , wherein the loupe and the camera in the extended position have the same optical axis.

5. The optical system according to claim 1 , further comprising a processor for controlling the camera.

6. The optical system according to claim 1 , further comprising at least a button for manually operating said camera for producing pictures and/or videos of the object.

7. The optical system according to claim 1 , further comprising at least one telecommunication port for transferring pictures and/or videos produced from said camera to a remote storing unit and/or for displaying in real time said pictures and/or videos from said camera on a remote display.

8. The optical system according to claim 1 , further comprising a remote storing unit for storing pictures and/or videos produced from said camera.

9. The optical system according to claim 1 , further comprising at least one light source disposed on the frame for illuminating the object.

10. The optical system according to claim 1 , further comprising a distance sensor for measuring the distance between the camera and the object.

11. The optical system according to claim 10 , further comprising an alert system for alerting the user if the measured distance between the camera and the object is smaller than a focal length of the camera.

12. The optical system according to claim 1 , further comprising a transparent digital display disposed on the lens and is arranged for displaying in real time pictures and/or videos imaging by said camera when the camera is on and for being transparent when the camera is off.

13. The optical system according to claim 12 , wherein the transparent digital display comprises an obscuring layer configured to be opaque when the camera is active for displaying in real time pictures and/or videos imaging by said camera and for being transparent otherwise.

14. The optical system according to claim 2 , wherein the handle further houses a telescopic pod pivotally movable between a retracted position in the handle and an extended position wherein the telescopic pod is spaced away from the handle and arranged to position the camera at a distance from the object to obtain a same field of view seen by an eye of a user directly through the lens.

15. The optical system according to claim 1 , wherein the transparent digital display comprises an obscuring layer configured to be opaque when the camera is active for displaying in real time pictures and/or videos imaging by said camera and for being transparent otherwise.

16. The optical system according to claim 1 , further comprising at least one light source disposed on the frame for illuminating the object, and the at least one light source is an LED or an OLED.

17. The optical system according to claim 16 , wherein the light source is operated continuously.

18. The optical system according to claim 16 , wherein the light source is operated pulsed synchronized with a frequency of acquisition of the camera.

19. The optical system according to claim 16 , wherein the light source is operated in flash mode.
