Significant deficiencies exist in the laser source technology for IRCM, specifically in the limited pulse rep-rate capability, limited average power output and capability to be transitioned to field environments. We propose a diode pumped solid state Er,Ho:YSGG laser and optical parametric oscillator to resolve these deficiencies. This laser has a potential dual use market in micro-surgery where t ...

With new detectors capable of sensing 7.5 - 9 micron wavelengths, a future threat is emerging since these detectors can be used in seekers. The need is to counter this threat with a laser source operating at 7.5 - 9 microns. The source requirements are 5 - 10 Watts of average power and a repetition rate of > 10 kHz. The proposed laser source is a Nd:YAG-pumped tandem OPO system consisting o ...

For future long-range theater ballistic missile defense, aircraft-mounted LADAR systems require eyesafe laser transmitters that produce higher pulse energy and better beam quality than currently available optical parametric oscillators (OPOs) pumped by diode-pumped Nd:YAG lasers. Aculight proposes a novel laser transmitter approach that can simultaneously generate the required pulse energy, b ...

Project objectives briefly described: i. Improve accuracy of measurement for cheating examinees by using a scoring method that takes account of the credibility of the examinee's patterm of wrong answers. ii. Provide an adjunct to on-line calibration that would assist in timing the replacement of items. iii. Identify test sites and recruiters that are associated with high rates of item compromis ...

The extension of classical frequency domain and wavelet transformation adaptive subband decompositions result in arbitrary time frequency til. The use of a time-varying tree-structured filterbank is proposed to provide a signal dependent transform which is capable of tracking non-stationarities via local reconfigurations. Under stationary assemptions, the filterbank converges to a unitary operat ...

Cured aircraft composite materials present a particularly difficult challenge for recycling technology. Those materials have mostly thermosetting epoxy matrices and occur in intimate association with metals, paints, and coatings. Current techniques for recycling thermoset composites, mostly for automotive sheet molding compounds (SMC), involve pulverizing the material for use as fillers. Th ...

A novel tertiary recycling process is proposed for investigation as an economical means for recycling shipboard plastic waste. Early development work has shown that this process can convert a wide variety of polymers and composites into low molecular weight hydrocarbons at temperatures below 200'C. The hydrocarbons produced can then be reused as chemicals, fuels, or monomers. Metal, glass, and fil ...

THE OBJECT OF THIS EFFORT WILL BE A REDUCTION IN WEIGHT AND PRODUCTION COSTS, RELATING TO THE CURRENT 5.56 BRASS CASED AMMUNITION CARRIED BY THE U.S. MILITARY FORCES. IT WILL INVOLVE THE EVALUATION OF MATERIALS AND DESIGNS USED BY AMMUNITION TECHNOLOGIES INC (A.T.I.) IN THE DESIGN AND CONSTRUCTION OF THE M193 PLASTIC CARTRIDGE CASE DEMONSTRATED AT FORT LEWIS WASHINGTON IN SEPTEMBER OF 1988. THESE ...
