Paper Abstract
The capability to detect, observe, and positively identify people at a distance is important to numerous security and
defense applications. Traditional solutions for human detection and observation include long-range visible imagers for
daytime and thermal infrared imagers for night-time use. Positive identification, through computer face recognition,
requires facial imagery that can be repeatably matched to a database of visible facial signatures (i.e. mug shots). Nighttime
identification at large distance is not possible with visible imagers, due to lack of light, or with thermal infrared
imagers, due to poor correlation with visible facial imagery. An active-SWIR imaging system was developed that is
both eye-safe and invisible, capable of producing close-up facial imagery at distances of several hundred meters, even in
total darkness. The SWIR facial signatures correlate well to visible signatures, allowing for biometric face recognition
night or day. Night-time face recognition results for several distances will be presented. Human detection and
observation results at larger distances will also be presented. Example signatures will be presented and discussed.
