Reveo has invented novel thin-film circular polarizer technology that is suitable for harsh space and industrial environments. This technology is based on rotating inorganic birefringent thin films of refractory metal oxides obtained with an innovative variation of conventional vacuum deposition techniques. The polarizers have unprecedented high performance: high operating temperature well above 1 ...

Laser radar (LADAR) is an emerging technology with the inherent ability to rapidly acquire high resolution range data day or night. Unfortunately current LADAR ranging techniques require an intense, focused beam that is mechanically scanned over a field of view. Mechanical scanning limits the data rate, is weight- and cost-prohibitive for many applications, and can be failure-prone. Scanned range ...

Head-mounted displays (HMDs) have been shown to assist the pilot in evaluating information from an increasing number of remote sources. With the development of subtractive color liquid crystal displays (SCLCD), color information can be used as an additional parameter to convey information to the pilot. Unfortunately, the image locations for the three primary colors of current SCLCDs are displaced ...

For missile guidance applications, there is a need for an infrared (IR) zoom lens that is compact, light-weight and environmentally rugged. In this program we will design an innovative IR zoom lens concept that uses lateral displacements of non-traditional optical elements to implement the zoom effect. The zoom lens consists, in part, of two lateral-shift, variable-focus lens groups. Our prelim ...

Diffractive optics is a promising technology for the aberration correction, athermalization, and achromatization of imaging systems. Diffractive optical elements (DOEs) can also be used for the generation of fanout arrays, microlens arrays, anti-aliasing gratings, and polarization optics. Applications include the fabrication of sports and military optics such as light-weight binocular eyepeices ...

The proliferation of portable electronic devices (cellular phones, laptop computers, personal digital assistants, and the like), in both military an civilian applications, provides a strong incentive to develop more efficient DC to DC power conversion technologies. Power dissipation in switching transistors and conduction losses in parasitic elements continue to limit conversion efficiencies. Al ...

Improvements in submarine stealth have necessitated development of improved sonar systems. The requirements of these systems suggest the need for a novel sensor technology which can simultaneously satisfy the demands of smaller size, lower cost, greater versatility, and enhanced performance. The new technology of microelectromechanical systems (MEMS) may offer an ideal solution to sonar needs ...

U.S. military forces are becoming increasingly involved in a variety of actions such as counter-terrorism, counter-drug, disaster relief, and nation assistance [collectively termed Operation Other than War(OOTW)] that have much in common with civilian law enforcement (LE). Consequently, military OOTW and civilian LE have overlapping technology needs---one of the most important of which is effecti ...
