The proposed effort is to design a space-qualified dual-frequency GPS/GLONASS receiver with enhanced capabilities for atmospheric remote sounding. While such soundings have been performed using GPS-only receivers, a space-based GPS/GLONASS receiver would be superior in terms of coverage and integrity cross- checking, as well as the ability to process the unencrypted GLONASS L2 signal. This design ...

Two-dimensional measurement machines, such as microlithography and computed tomography systems, are subject to distortions in the measurement field due to imperfections in their hardware and software. Certified methods to characterize and quantify such distortions are urgently needed. An innovative self- calibrating scheme is tendered which eliminates the disadvantages of previous self-calibration ...

In response to the increasing demand for better understanding of the manufacturing processes and the machining systems, a new testing standard--ASME B5.54 and a family of new testing instruments have been developed for evaluating the performances of a variety of CNC machining centers. Because of the advancement and versatility of the new instruments, test data are being collected at a much higher ...

We will develop technology, termed a Ruggedized Wind Measurement System (RWMS), to measure directly extreme winds with high space and time resolution, focusing on the winds that occur beneath hurricanes at land fall. This development effort will include design, fabrication of two prototype RWMS units, and a series of proof-of-concept demonstrations in strong mountain-induced downslope and severe t ...

Precision underwater mapping is an important requirement of projects ranging from wreck surveys and environmental impact studies to mine clearing operations and marine science projects. Small Autonomous Underwater Vehicles (AUV) are capable platforms for mapping operations as they are easily deployed and can operate in hazardous environments. We propose the development of an Automated Imaging and ...

Fire fighter burn injuries continue to be a frequent problem despite significant advances in protective clothing. A reason for this is the buildup of moisture in fire fighting garments as a result of sweating or fire fighting activities. This buildup of moisture increases the heat transfer through the garment and can result in scald burn injuries as the water is quickly heated. Currently, there is ...

The storage photostimulable phosphor (SPP) technique has been demonstrated to be sensitive to ionization radiation. It is especially suited for detecting alpha particles since the efficiency is practically 100%. In addition to being able to quantify total ionization deposited in a SPP sensor, it also captures the radiation source distribution information in a digital image which can be readily ana ...

Critical issues associated with the design of a rugged, compact "real time" sampling system using photoconductive switches as the signal generator and sample will be investigated. The design concept is based upon an optoelectronic equivalent time sampling principle developed by the Principal Investigator. It involves first the phase locking of the temporal waveform to be measured to the optical pu ...

We propose to develop an innovative, compact ultrafast high brightness laser source, broadly tunable in the infrared for vibrationally-resolved infrared microscopy and other applications. By passive Kerr lens mode-locking of a novel diode-pumped tunable Cr:LiSAF laser, 100fs pulses will be generated at 100 MHZ repetition rate with an average power of 1W. An optical parametric oscillator (OPO) pump ...
