Night vision arrangement
First Claim
1. A night vision arrangement for a vehicle, the night vision arrangement incorporating a camera, the camera comprising a lens, and an infra-red sensor to capture an image received through the lens, therebeing a display unit to display the captured image to a driver of the vehicle, characterised in that the lens defines an optical axis, and within the camera a beam deflector is provided in alignment with the optical axis adapted to deflect the beam received through the lens and to direct the deflected beam on to the said sensing means.

Abstract
In a night vision arrangement for a motor vehicle a camera (1) is provided which captures an image which is subsequently displayed on a display arrangement (3) which may be a head-up display arrangement. The camera (1) has a lens (4) which is aligned with a beam deflector (6) which may be constituted by a mirror (7) which deflects the beam so that is passes along a neck (8) on to a sensor (11). The camera may relatively easily be mounted in position in a motor vehicle.

22. A device for the enhancement of night vision in a vehicle like an automobile including an infra-red camera, comprising a lens and an infra-red sensing means, mounted on the vehicle to view the roadway in front of the vehicle, generating a video signal representing the thermal image of the roadway, a processing unit and a display unit to make the image visible to the vehicle operator, characterised in that the lens is mounted on an elongated neck portion of the device, comprising optical means for conveying the infra-red radiation to the infra-red sensing means.
