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 ...

The rapid development of the technology for producing high quality single crystal SiC wafers and thin films presents the opportunity to fabricate solid-state devices with power-temperature capability far greater than devices currently available. While conventional silicon power devices are already being used near their limits of operating temperature and power, the potential of SiC is just beginni ...

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 ...

This proposal deals with a number of Si quantum devices employing the patented Strain-layer Superlattice Barrier (SLS-B) serving as barrier quantum confinement in silicon. These barriers normally consist of, for example CaF(2)/Si/Ca(2), A1(2)O(3)/Si/A1(2)O(3) or SiO(2)/Si/SiO(2). Our emphasis is on a SiO(2)/Si/SiO(2) SLS-B as a superlattice barrier for Si quantum wells. The proposed work involves ...

Thermal conductivity of diamond can be greatly improved by reducing the (12)C and (13)C initiated phonon collisions. Removal of (13)C isotope from CH(4) in the Arc-jet CVD produced diamond would drastically improve the thermal management in devices ranging from the nose-cones of missiles to multichip modules. Isotope enrichment of (12)C, or the removal of (13)C, uses a chemical diffusion process ( ...
