A lidar laser transmitter useful for profiling of clouds, aerosols, and differential absorption measurements of atmospheric trace constituents such as carbon dioxide, water vapor, and ozone is proposed. The proposed laser transmitter is based on a master tunable external cavity diode laser (ECDL) used to injection lock a series of free running laser diodes (FRLD's). The FRDL's amplify the injected ...

This project will design and deliver a high accuracy monitor for the photo-chemically coupled pollutants nitric oxide, nitrogen dioxide and ozone using infrared absorption spectroscopy with quantum cascade (QC) lasers. The target molecules are monitored at air quality stations worldwide using instruments which require frequent calibration and are subject to significant chemical interferences (in t ...

The present invention provides an inexpensive and low loss fiberoptic manifold for lightweight, high-efficiency, electronically steerable, phased-array antennas. Our approach is sate-of-the-art in design and closely coupled with proven volume fiber optic component manufacturing techniques, holding a promise of realizing practical optical digital delay with performance and cost that have not been a ...

Solid-state light sources promise many advantages over traditional technologies. Among these advantages is the ability to construct a source whose relative spectral distribution can be tuned to better match a desired spectrum. We propose addressing this technical and market opportunity through the development of a novel single-chip semiconductor device which delivers high optical output power (>20 ...

The use of thermal neutrons has been widespread over the past several decades in many investigations such as non-destructive testing (NDT), neutron radiography and macromolecular crystallography. For some applications such as crystallographic diffraction studies, neutrons are scattered over 4o in space and an ideal detector would be able to image the scattered radiation on a spherical surface. Cur ...

CCDs (Charge-Coupled Devices), and more recently, CMOS (complementary-symmetry metal-oxide-semiconductor) APS (Active Pixel Sensor) cameras have revolutionized imaging instrumentation and the many fields that utilize these instruments. Both of these technologies rely on detecting, or integrating, the analog photo-current generated in each pixel, which limits their sensitivity and bandwidth. Counti ...

This Phase I SBIR describes the fabrication and characterization of a position sensitive detector with internal gain. During this program, Radiation Monitoring Devices (RMD) will fabricate several position sensitive avalanche photodiodes (APDs), including both quadrant and lateral-effect photodiodes. Using RMD's advanced planar processing technology, the position sensitive detectors will be optimi ...

ALTAIR Center proposes to develop a new class of nano-electro-mechanical systems (NEMS) based on carbon nanotubes operating at low control voltages. The proposed system consists of thin film of an appropriate solid-state material sandwiched between two nanolayers of carbon nanotubes embedded into a special matrix. The device takes advantage of recently demonstrated effect of elongation or contract ...

This project builds on experience in an SBIR phase I project which successfully determined that the particle transport code Geant4 could be applied to the simulation of biological shielding. Among the many lessons learned during phase I was that while the physics and functionality embodied in Geant4 is either already excellent, or clearly extendible as needed, the great lacuna lies in its ability ...
