NIGHT VISION ARRANGEMENT
First Claim
Patent Images
1. A night vision arrangement for a vehicle, the night vision arrangement comprising:
- a camera, the camera comprising an optical element which is substantially transparent to at least infra-red light, the optical element defining an optical axis, the camera further comprising an infra-red sensor to capture an image received through the optical element, and a beam deflector in alignment with the optical element adapted to deflect a beam received through the optical element and to direct the deflected beam on to the sensor; and
a display unit to display the captured image to a driver of the vehicle, part of the camera contains the sensor being mounted within a main envelope of the vehicle in with the optical element, when in an operative position, being beyond said envelope, the beam deflector comprising a mirror wherein a part of the camera containing the sensor is mounted within the vehicle, with the optical element being positioned or positionable on an exterior of the vehicle.

Abstract
In a night vision arrangement for a motor vehicle a camera is provided which captures an image which is subsequently displayed on a display arrangement which may be a head-up display arrangement. The camera directs light on to a beam deflector which may be constituted by a mirror which deflects the beam so that it passes along a neck on to a sensor. The camera may relatively easily be mounted in position in a motor vehicle.

16. A device for the enhancement of night vision in a vehicle like an automobile comprising:
-
an infra-red camera for being mounted on the vehicle to view an area in front of the camera, and generating a video signal representing a thermal image of the area, the camera comprising an optical element for passing light therethrough, and an infra-red sensing means for sensing the light passed through the optical element, and an optical means having an elongated neck and conveying infra-red radiation received through the optical element to the infra-red sensing means;
a processing unit for processing signals from the sensing means; and
a display unit coupled to the processing unit for making an image visible to a vehicle operator, wherein the optical means comprises a mirror that deflects the light wherein a part of the camera containing the sensor is mounted within the vehicle, with the optical element being positioned or positionable on an exterior of the vehicle.
