Abstract
The utility of Near-Infrared (NIR) sensors for Enhanced Vision System (EVS) applications has been identified and well documented. In particular, such sensors are well suited to detecting runway approach lighting, and often outperform the pilot's vision for this task. We present the results of field tests of very low cost NIR sensors, based on sensitive visible-light cameras, for this application; the cost/benefit tradeoffs of these sensors are so favorable that they may well form the core of a basic EVS system, or an effective enhancement to EVS systems based on other primary vision sensors. Useful processing techniques for imagery from these sensors, in the presence of cooperative sensors, or as a standalone system, are also presented.
