THE OBJECTIVE OF THIS RESEARCH IS TO SEE IF AN EXTREMELY NARROWBAND SODIUM FARADAY ATOMIC LINE FILTER CAN BE USED TO ALLOW ADAPTIVE SYSTEMS USING A SODIUM LASER GUIDE STAR TO WORK UNDER DAYTIME LIGHT CONDITIONS FOR APPLICATIONS SUCH AS IMAGING SATELLITES. THE POTENTIAL APPLICATIONS OF THE FILTER… More

THIS PROPOSAL IS FOR THE DESIGN OPTIMIZATION AND TESTING OF A HIGH CURRENT SHEET-LIKE ELECTRON BEAM GENERATOR. SPECIFICALLY IT IS FOR A HIGH CURRENT DENSITY (>20A/CM2) SHEET ELECTRON BEAM SOURCE USING A RUGGED LaB(6) CATHODE. SHEET ELECTRON BEAMS ARE VERY DESIRABLE FOR COUPLING TO THE EVANESCENT… More

DIAMOND HAS A NEGATIVE EELCTRON AFFINITY ON ITS (111) FACE AND P-TYPE DIAMOND IS CONDUCTIVE. UNFORTUNATELY, DOPING OF DIAMOND TO MAKE IT CONDUCTIVE DECREASES THE CARRIER MOBILITIES WHILE INCREASING THE TRAP DENSITIES. EXPERIMENTS WITH P-TYPE DIAMOND HAVE NOT YET PRODUCED SIGNIFICANT CURRENTS. IN THE… More

THIS PROPOSAL IS FOR THE STUDY AND DEVELOPMENT OF A COMPACT, HIGH POWER TUNABLE MILLIMETER WAVE GENERATOR. SPECIFICALLY IT IS FOR A COMPACT OROTRON TUBE OPERATING IN THE 94 GHz (W-BAND) RANGE WITH POWER OUTPUTS ON THE ORDER ON 10 WATTS. SUCCESSFUL DEVELOPMENT OF THE OROTRON DEVICES DEPENDS… More

The primary objective of this research is to develop a novel optical multiplexing/demultiplexing device to combine many separate laser channels for communications applications. For both free space and fiber optic laser communications it is desirable to have a multiplexing scheme which has many… More

The primary objective of this Phase I technical effort is to desgin, prototype and measure the performance of a novel compact gimbal that is specifically designed for high precision pointing of electro-optic systems from mobile platforms. This novel gimbal consists of two rotating joints oriented at… More

The objective of this effort is to demonstrate a novel method of generating a volumetric three-dimensional display. This method uses intersecting lasers in a gaseous medium to cause fluorescence from desired points. By scanning a series of intersection points in either a rastor or vector scan in a… More

The objective of this research is to design and implement error-correction coding in a free-space laser communication channel to correct both single bit and burst errors at a user data rate of 155 Mb/s. Correcting these errors will significantly increase the reliability and weather-dependent… More

This method uses intersecting lasers in a gaseous medium to cause fluorescence from desired points. By scanning a series of intersection points in either a rastor or vector scan in a… More

The ultimate objective of this research is to develop a low cost, high bandwidth, quickly deployable communications system. The system relies on 10-20 Mbps RF communications within a 100 m diameter cell size. The cells are interconnected with 622, Mbps optical crosslinks. The critical technology in… More

The objective of this research is to investigate the use of photon-counting avalanche photodiodes as a laser communication sensor. This detector technology allows reduction of the received optical power. The system will also incorporate a cesium atomic line filter to eliminate background light and a… More

Not Available BMDO has been entrusted with the responsibility of protecting citizens and assets from missile attack. Many of the systems developed under BMDO¿s TMD and NMD focus areas require high speed correlation, often in a compact package. The performance requirements of high-end BMDO… More
