Abstract
A testing apparatus for determining the enhanced vision capabilities of a system that is designed to assist a pilot in detecting lights and ground features in night and low visibility conditions. One embodiment of the apparatus is suitable for laboratory or production facilities, the other embodiment is used for the flight line by installing it in the aircraft. A simulated pattern is presented by the apparatus wherein the enhanced vision system (EVS) can be calibrated. Further, fog can also be simulated over the spectral band of the EVS. Runway landing lights are also able to be simulated using a readily available light source.
