Abstract

An optical viewing system includes an optical viewing device in a housing having a socket at its inner end for application to a person'"'"'s finger, a focussing lens at its outer end for focussing images in the region in front of the focussing lens, and an image sensor for transforming the images to electrical signals. A remote monitor unit receives the electrical signals and displays the images received by the image sensor.

Claims

1. An optical viewing device, comprising:

a housing including a focussing lens and an image sensor for receiving optical images from said focussing lens and for transforming the images to electrical signals;

characterized in that said housing includes a socket at one end, constituting the inner end of the housing, for application to a person'"'"'s finger; and

said focussing lens is mounted at the opposite end of the housing, constituting its outer end, for focussing optical images in the region in front of the focussing lens on the image sensor.

2. The device according to claim 1, wherein said housing further includes a light source for illuminating the region in front of the focussing lens.

3. The device according to claim 2, wherein said housing further includes a light switch for controlling the energization of said light source.

4. The device according to claim 3, wherein at least the end of the housing including said socket is of flexible material permitting it to conform to the shape of the user'"'"'s finger.

5. The device according to claim 4, wherein said light switch includes an actuator, and said housing includes a flexible portion which overlies said actuator so as to permit energization of the light source by manually depressing said latter flexible portion of the housing.

6. The device according to claim 5, wherein said housing includes a further electric switch controlling the energization of said viewing device, said further electric switch also including an actuator underlying said flexible portion of the housing permitting energization of the viewing device by manually depressing said latter flexible portion of the housing.

7. The device according to claim 1, wherein said housing is carried by a single socket for application to a single finger of the user.

8. The device according to claim 7, wherein said housing further includes a wrist strap for securing the housing onto the user'"'"'s finger.

9. The device according to claim 1, wherein said housing is made of flexible material.

10. The device according to claim 1, wherein said housing is carried by a glove of flexible material having a plurality of finger sockets for application to the user'"'"'s hand.

11. The device according to claim 1, wherein said housing further includes a battery for energizing said image sensor.

12. The device according to claim 11, wherein said battery is of the rechargeable type, and said housing includes a charging circuit comprising a charging secondary winding adapted to be placed in close proximity to a charging primary winding of an external charging circuit in order to recharge said battery.

13. The device according to claim 11, wherein said housing further includes an RF transmitter and antenna for transmitting the electric signals from said image sensor.

14. The device according to claim 13, in combination with a monitor including an RF receiver and antenna for receiving said electric signals transmitted by the optical viewing device.

15. The device according to claim 1, in combination with a monitor wire-connected to the output of said image sensor.

16. The device according to claim 1, wherein said image sensor is a CCD.

17. An optical viewing system comprising:

an optical viewing device; and

a remotely-located monitor device;

said optical viewing device comprising a housing including;

a socket at one end, constituting the inner end of the housing, for application to a person'"'"'s finger;

a focussing lens at the opposite end of the housing, constituting its outer end, for focussing optical images in the region in front of the focussing lens;

and an image sensor within the housing for receiving optical images from said focussing lens and for transforming the images to electrical signals;

said monitor unit including an optical display for displaying the images received by said image sensor.

18. The system according to claim 17, wherein said optical viewing device further includes a light source for illuminating the region in front of the focussing lens, and a light switch for energizing said light source.

19. The system according to claim 17, wherein said optical viewing device further includes an RF transmitter for transmitting the electric signals from the image sensor;

and said monitor unit includes an RF receiver for receiving said transmitted RF signals and for feeding them to the display.

20. The system according to claim 17, wherein said monitor unit is wire-connected to said optical viewing device.
