Abstract

An optical assembly is provided that allows a user to view objects with normal perspective and scale under conditions of total darkness, in daylight, or other conditions limiting normal vision, or adverse weather conditions. The optical assembly includes a white light flashlight, with a filter cap mounted to the illuminating end of the flashlight. The filter cap permits infrared light in the appropriate range of 900 to 1200 nanometers to pass through. The optical assembly further includes a camera pack including a camera, and preferably including a transmitter. Said camera pack attached to the flashlight and in communication with a display mounted to a head gear worn by the user so that the screen of the display is directly in front of an eye of the user. The camera lens of the camera pack and the illuminating end of the flashlight are aligned along a single linear optical axis. The camera pack communicates with the display via a communication means when wireless communication is not preferred. The optical assembly includes a receiver coupled to the display when wireless communication is preferred, said receiver permits wireless transmission of images from the transmitter disposed within the camera pack. The receiver will also provide wireless communication between the receiver and a remote source equipped with a transmitter.

In use, the object under surveillance is targeted by the illuminating light of the flashlight. A portion of the light is filtered by the filter cap, and a portion is passed through the filter cap to the object, the camera receives the light reflected off the object and generates a video signal to the display responsive to the received light, for which may be viewed by the human eye.

Claims

1. An optical assembly for viewing at night, in daylight, or under other vision impaired conditions, said optical assembly comprising:

a camera pack having image generating circuitry mounted therein and including a camera having a lens, said camera pack attached to a white light flashlight, the flashlight having an illuminating end,

a filter lens mounted to the illuminating end of the flashlight, said filter lens receiving light from the flashlight and reflecting light off an object in a first direction,

a display a having display board and display circuitry mounted therein, said display in continuous communication with said camera pack,

said camera pack for receiving said light reflected off the object and generating a video signal responsive to said received light,

said display to couple said video signal transmitted from the camera pack to an eye of a user,

wherein the lens of the camera pack and the illuminating end of the flashlight are aligned along a single linear optical axis,

connection means for connecting the camera pack to the display,

a power means for powering the camera pack.

2. The optical assembly as recited in claim 1, further comprising a receiver having a multi-channel receiver board.

3. The optical assembly as recited in claim 2, wherein the camera pack further including a multi-channel transmitter, wherein the transmitter is in wireless communication with the receiver.

4. The optical assembly as recited in claim 3, further comprising a head gear having a front side and a back side, wherein the display is pivotally attached to the front side, and the receiver is attached to the back side.

5. The optical assembly as recited in claim 1, wherein the power means is a battery.

6. The optical assembly as recited in claim 1, wherein the filter cap permits infrared light in the range of 900 to 1200 nanometers to pass through.

7. The optical assembly as recited in claim 1, wherein the display further comprising a rear housing having a recessed portion and a back surface, a quick mount ring positioned on the recessed portion of the rear housing, a flexible goose neck having a first end and a second end, wherein the second end is attached to the quick mount ring with a clamp and thumb screw, and the first end of the goose neck attached to a display mount, an inner cord relief having a center aperture and a plurality of screw apertures for attachment to an outer cord relief having a center aperture and a plurality of screw apertures, wherein the screw apertures of the inner and outer cord reliefs are in alignment, wherein the center apertures of the inner and outer cord reliefs are in nonalignment, said center apertures of the inner and outer cord reliefs for receipt of said connection means, wherein an outer surface of the outer cord relief defines the back surface of the rear housing of the display.

8. An optical assembly for viewing at night, or daylight or under other vision impaired conditions, said optical assembly comprising:
