There is a serious need for new types of position sensors for use with adaptive optics systems which employ segmented mirrors. In particular, sensors which enable the system to control and maintain the phase matching of the mirrored surfaces of adjacent segments to accuracies of a few nanometers are needed. Blue Line Engineering Co. proposes to develop a novel type of sensor which will be suitable ...

Cryogenic radiometers are the primary standards for the measurement of power in the infrared, the visible, and the ultraviolet, a large part of the ueful spectrum. The integrity of the DoD procurement process and of DoD technology development depend critically on these standards. One aspect of this dependence is measuring the characteristics of those devices that work well in battle. Those measure ...

High power diode-pumped 2 micron lasers are of great interest for a variety of lidar applications, including long range hard target tracking and space-based coherent laser radar systems operating in the eye-safe region of the spectrum. Lidar modeling suggests that 0.5-1 J/pulse energies at pulse repetition frequencies of about 40 Hz will be sufficient to meet many lidar mission requirements. CTI h ...

Passive two-phase heat transport systems, specifically heat pipes and more recently, Capillary Pumped Loops, have been successfully applied to spacecraft thermal management. Loop Heat Pipes, developed in the former Soviet Union, offer the design engineer another alternative, one which combines the reliable, self-starting features of the heat pipe, with the high heat transport capacity and antigrav ...

We have devised a new type of "intelligent" optical fiber receiver able to tolerate inevitably time-varying wavelength shifted data. This robust optical fiber receiver will make WDM high-performance data transfer systems and even systems designed to operate in harsh environments very economical. The proposed receiver, which is also manufacturable and robust, is a suitable component for both packet ...

We propose a systematic investigation of crystalline Si structures as their dimensions are reduced to quantum sizes (5-10 nm). For convenience, we have chosen Si on insulator (SOI) material for optical and electrical characterization. Our nanofabrication approach relies on simple laser interferometric lithography techniques that are uniquely adaptable to large area manufacturing. Suitable applic ...

Future flight vehicles will require incredased speed, precision, and survivability under a wider variety of flight conditions than current technology supports. The traditional role of flight control systems (FCS) in providing stability and command augmentations must be expanded to achieve enhanced maneuverability, combat effectiveness, and self repair. Recent advances in the development of fuzzy l ...
