Physical Optics Corporation (POC) proposes to develop an innovative high Resolution Acousto-optic Imaging Sensor (RAIS) device based on limitations of existing technologies for underwater imaging. The compactly packaged RAIS device comprises an AOLCD, ultrasound generator, acoustic lens, and CCD camera. The acoustic ultrasound transducers produce ultrasonic waves. The acoustic waves propagating ...

Current advanced as well as future electronic data communications and signal processing requirements for military as well as commercial applications need the operations of analog to digital converters (ADCs) with performances beyond that of commercially available designs. In this Phase I proposal, PRI will develop the architectural design for a new integrated circuit chip set to be housed in a s ...

Recent years have seen the size of GPS receivers shrink dramatically due to higher levels of integration. A GPS receiver consists of a combination of RF and IF circuitry, filters, analog to digital converts (ADC) and a digital Signal Processor (DSP) engine. One of the remaining factors preventing further integration is the necessity of a Surface Acoustic Wave (SAW) filter and dielectric filters. ...

Technical Abstract (Limit your abstract to 200 words with no classified or proprietary information/data.) Epitaxial Release (WSER) Technique for Multifunctional Optoelectronic Chip Module On Si substrate. Unlike conventional epitaxial lift-off technique which only allow limited die size bonding and selective etching on AlGaAs only, PKR's direct InGaP/GaAs wafer-scale bonding technique will achieve ...

It is well known that Gen III image intensifiers based on Negative Electron Affinity (NEA) photocathodes and micromechanical plates suffer from a major limitation of having the long wavelength cutoff limited only to about 950 nm. For that reason, it has poor modulation transfer function and correspondingly lower performance in starlight and in the overcast starlight levels. To develop a new type ...

The proposal is to develop a high frame rate imaging system for combustion and other research, by combining a solid state camera capable of capturing images of transient photometric phenomena at framing rates up to 1,000,000 frames per second with the laser sheet illumination technology that has been developed by the Propulsion Directorate of Phillips Laboratory. Both instrumental technologies ar ...

The state-of-the-art in magnetoresistive sensors has improved to a point where they can be used to construct extremely sensitive, room temperature, multi-axis magnetic gradiometers. Typical magnetoresistive elements have a white noise floor of 5 pT/Hz(square root), and operate with flat response from DC to tens of MHz. A light weight, inexpensive, multi-axis gradiometer could be constructed from ...

RD Instruments has several acoustic sensor technologies which are on the threshold of achieving the affordability, low-power, robustness, and miniaturization needed for autonomous underwater vehicle (AUV) applications. We manufacture Acoustic Doppler Current Profilers (ADCPs), Doppler Velcoity Logs (DVLs), and Correlation Velocity Logs (CVLs). We are also developing a phased array sonar in which ...

Distributed Packet Radio (DPR), originally developed by ARPA due to its clear benefits for the military, has not yet enjoyed the cost reductions and improvements that would result from wide-spread commercial adoption. This lack of commercial adoption of DPR is not, however, due to a lack of commercial uses for DPR. In fact, a huge variety of applications could benefit greatly from the unique fea ...

Packet radio technology, originally developed by DARPA due to its clear benefits for the military, today has the potential for wide-spread adoption by a variety of commercial markets. Such commercial nomadic routers, which we call Internet Radios, promise to offer a new and unique set of capabilities for regional- and campus-area networks: self-managing peer-to-peer communication with rapid, wire ...
