ILARTS Imaging Sensor for Day/Night Aircraft Approach and Landing
Abstract
Television cameras utilized by aircraft carrier Landing Signal Officers (LSO) need to provide good imagery, day and night, under conditions where the aircraft is illuminated by ambient light but the aircraft's bright landing lights are on, resulting in intra-scene dynamic range of -10E6. These TV cameras provide the LSO with glide-slope and lineup information, and also view deck operations, approaches, and launches. This application, vital to aircraft carrier operations, needs a television image sensor and camera system to replace the Image Isocon based cameras which are no longer manufactured. The television image sensor affording the necessary dynamic range is the Charge Coupled Device(CCD). Their high quantum efficiency and low readout noise make CCDs competitive at low illumination levels with intensified image sensors and provide superior performance at moderate and high light levels. The conclusion of this Phase I study is that a camera based on back illuminated CCD technology can match and in some cases exceed the benchmark Image Isocon camera performance in the demanding ILARTS application.
