Multi-camera closed circuit television system for aircraft
First Claim
1. An airborne closed circuit television system which comprises a first camera, said first camera equipped with a zoom lens, said first camera arranged to have a field of view essentially perpendicular downward from the aircraft'"'"'s centerline, said first camera including said zoom lens and other associated optics, a focal plane sensor and an interface electronics unit to condition the output of the focal plane electronics for transmission to an external camera control unit;
- a second camera arranged essentially parallel to the aircraft'"'"'s center line and forward facing, said second camera also incorporating camera lens optics, a focal plane sensor and interface electronics;
a camera module unit structure which houses the two cameras in relation to one another, the system arranged to provide fields of view which narrowly avoid imaging the adjacent camera;
a window mounted within said camera module unit providing a field of view of the cameras, said window provided with means to heat said window;
means to heat at least one component of said cameras;
a remote camera control unit containing electronics to drive and process information from the camera; and
a remote control unit in the flight deck of the aircraft which allows control of the functional aspects of the system by a member of the flight crew.
