Non-invasive methods are required to measure the turbulence in supersonic jet plumes in 3-D with high temporal and spatial resolutions. The turbulent supersonic jet plume changes rapidly both in space and time, and hence any viable approach must acquire the entire 3-D velocity field at even faster… More

Military common laser range finders (CLRF) currently use a direct viewing binocular augmented with AN/PVS night vision eye pieces with infrared cutoff at about 900 nm, incapable of detecting either the eye-safe laser range finder beam or the laser designator beam. The CLRF needs an all-light-level… More

Ground resolution is a critical parameter of an airborne surveillance system, whether it is a ground radar or an optical camera. The synthetic aperture (SA) method has proven extremely successful in Radio Frequency (RF) radars to achieve spatial resolution significantly higher than that of the… More

Almost all intelligence, surveillance, and reconnaissance (ISR) platforms and all small agile munitions need high-sensitivity night vision imagers for situational awareness and for target identification, tracking and discrimination. The requirements of situational awareness, responsiveness and… More

ABSTRACT: Currently fielded night vision goggles intensify images in an integrated components train comprising a photo cathode, a multi-channel plate for amplification, and a phosphor screen. A purely semiconductor-based night vision device with higher performance, longer lifetime and lower cost is… More

ABSTRACT: Infrared thermography has been increasingly used for the measurement of surface temperature and convective heat transfer characteristics of combustion engines. The infrared thermometry technique is particularly advantageous for resolving spatial and temporal surface temperature… More

An ever-changing battlefield poses a growing threat of small arm hostile fire for our ground troops, ground vehicles and low-flying airborne platforms. High performance and low cost hostile fire indicator (HFI) solutions are needed to protect both stationary posts and moving military platforms.… More

Battlefield medicine has been a critical component of any successful military campaign since ancient times. A safe, secure, wireless, high data rate communication link is highly desirable for tactical battlefield casualty management. One promising solution is the free-space optical non-line-of-sight… More
