Imaging system range defines the maximal distance at which a selected object can be seen
and perceived following surveillance task perception criteria. Thermal imagers play a key …

The Johnson Criteria metric calculates probability of detection of an object imaged by an
optical system, and was created in 1958 by John Johnson. As understanding of target …

This paper is the first of three papers associated with the military benefits of SWIR imaging.
This paper describes the benefits associated with passive daytime operations with …

Recent development of active imaging system technology in the defense and security
community have driven the need for a theoretical understanding of its operation and …

Image-based sensing is a powerful source of information for a wide range of applications
such as surveillance, monitoring, and automation. The volume of data collected by …

Imaging system performance can be described in the spatial domain, where the optical blur
diameter is compared to the detector size, or in the frequency domain [modular transfer …

Daytime low-light conditions such as overcast, dawn, and dusk pose a challenge for object
discrimination in the reflective bands, where the majority of illumination comes from reflected …

Model-based performance assessment is a valuable approach in the process of designing
or comparing electrooptical and infrared imagers since it alleviates the need for expensive …

Long-range target identification is well studied in the visible (Vis) and near-infrared (NIR)
bands and more recently in the shortwave infrared (SWIR). The longer wavelength of SWIR …

Night vision for automobiles is an emerging safety feature that is being introduced for
automotive safety. We develop what we believe is an innovative new night vision system …
