Long-Range Imaging III.
Long-range video surveillance is usually limited by the wavefront aberrations caused by atmospheric turbulence, rather than by the quality of the imaging optics or sensor. These aberrations can be mitigated optically by adaptive optics, or corrected

Methods to reconstruct pictures from imagery degraded by atmospheric turbulence have been under development for decades. The techniques were initially developed for observing astronomical phenomena from the Earth’s surface, but have more recently b

Domain-specific languages are a useful tool for productivity allowing domain experts to program using familiar concepts and vocabulary while benefiting from performance choices made by computing experts. Embedding the domain specific language into an

Atmospheric turbulence degrades imagery by imparting scintillation and warping effects that can reduce the ability to identify key features of the subjects. While visually, a human can intuitively understand the improvement that turbulence mitigation

When capturing image data over long distances (0.5 km and above), images are often degraded by atmospheric turbulence, especially when imaging paths are close to the ground or in hot environments. These issues manifest as time-varying scintillation a

The use of commodity mobile processors in wearable computing and field-deployed applications has risen as these processors have become increasingly powerful and inexpensive. Battery technology, however, has not advanced as quickly, and as the process

Passive and Active Millimeter-Wave Imaging XVIII.
The transmission characteristics of millimeter waves (mmWs) make them suitable for many applications in defense and security, from airport preflight scanning to penetrating degraded visual environments such as brownout or heavy fog. While the cold sk

Many ISR applications require constant monitoring of targets from long distance. When capturing over long distances, imagery is often degraded by atmospheric turbulence. This adds a time-variant blurring effect to captured data, and can result in a s

Recently, new techniques for passive imaging based on distributed aperture imagers have been developed. One promising approach utilizes photonic sampling, routing, and processing of the millimeter-wave energy for image generation. Many signal process
