Abstract

Active imaging techniques such as continuous-wave (CW) illumination and laser range-gated (LRG) imagery can provide increased contrast-to-noise ratio over passively-illuminated systems under conditions with poor solar illumination and strong scattering. Additionally, the shortwave infrared (SWIR) and extended SWIR (eSWIR) bands have been shown to offer increased performance over VIS and NIR systems in these conditions. Our group at the University of Arizona has developed an active imaging testbed with capabilities in the SWIR and eSWIR in order to test and quantity these benefits in field imaging studies. We discuss the design of the testbed, and show imagery and performance calculations from our field collections.
