Abstract
A night vision system, suitable for vehicular use, including an infra-red detector mounted on a vehicle, a display mounted on the vehicle, a single-element lens mounted upstream of the infra-red detector so as to direct light from a scene onto the infra-red detector, and circuitry operative to receive a detector output from the infra-red detector and to provide an image output based on the detector output to the display. The system is suitable for applications other than vehicular use, where a comparatively narrow field of view is to be imaged.
Claims72
A vehicular night vision system comprising:
- an infra-red detector mounted on a vehicle;
- a display mounted on said vehicle;
- a focusing assembly for directing infrared radiation from a scene onto said infra-red detector, comprising a single-element lens, mounted upstream of said infra-red detector;
- and
- circuitry operative to receive a detector output from said infra-red detector and to provide an image output based on said detector output to said display.
A vehicle having night vision functionality comprising:
- a motor vehicle;
- an infrared detector mounted on said vehicle;
- a display mounted on said vehicle;
- a focusing assembly for directing infrared radiation from a scene onto said infra-red detector, comprising a single-element lens only, mounted upstream of said infra-red detector;
- and
- circuitry operative to receive a detector output from said infrared detector and to provide an image output based on said detector output to said display.
