In this program, Omega Optics and the University of Texas at Austin propose to develop an on-chip surface-enhanced Raman scattering (SERS) spectrometer array for single molecule detection. The sensitivity of the SERS spectrometer comes from the 5-nm gap between gold nanowires, which can achieve 108 enhancement factor (EF) for the Raman scattering signals. Especially, these gold nanowires are preci ...

The current produced in electrochemical galvanic cells is primarily dependent on the rate of the electrode reactions where the cell's anode is less negative, supplying less energy than thermodynamically predicted, and the cell's cathode is less positive, supplying less energy than thermodynamically predicted. Reduction of electrochemical overpotentials in electrochemical systems has been the prim ...

LADAR light reflection from a target is highly dependent of the spectral reflectivity and texture properties of the surface. Such dependencies could be exploited for target recognition based on surface characterization with appropriate imaging conditions and processing algorithms. Target surface light reflection is characterized by the Bidirectional Reflectance Distribution Function (BRDF), which ...

Physical Sciences Inc. (PSI) and Duke University propose to develop a hybrid, multifunctional, ultraviolet (UV) beam conditioner intended for laser beam switching, deflection, and frequency shifting for quantum computing applications. The beam conditioner consists of three functional blocks, separating the technology for frequency control, fast amplitude control, and electronic beam shuttering int ...

Physical Sciences Inc. (PSI) and its partners, Research Support Systems (RSI, a PSI-subsidiary) and Professor Thomas Strohmer of UC Davis, propose to develop an innovative approach that can be employed by an ‘on-the-move’ sensor constellation to determine the size (length, width, and height), absolute geo-location, and 3-D concentration distribution of chemical threat clouds released on battle ...

This effort is focused on establishing U.S. Army Corps leadership in preserving navigation access for the war fighter through the development and implementation of an acoustic-based sensor system to detect, track, and classify large aquatic animals. The proposed high frequency imaging active sonar system is configurable to detect, track, classify, and alert to the presence of threatened and endang ...

Hstar proposes a near autonomous combat casualty extraction robot (c2Exbot) system that: 1) supports autonomous dexterous manipulation, safe patient lifting and near autonomous navigation control, 2) utilizes a supervisory telepresence operation mechanism, 3) provides near autonomous patient diagnosis, injury assessment and emergency treatment, and d) provides semi-autonomous patient monitoring an ...

We will develop novel acousto-optic devices for use in the UV using the new material Barium Borate (BBO) which not only has the required UV transparency, but a unique combination of acoustic and optical properties. The capabilities provided by these new UV AO devices are ideally suited for optical addressing arrays of trapped ions with focused spots from appropriately tuned UV and visible lasers t ...

A narrow-band microbolometric detector is proposed to the address need for a low-cost, portable system to perform chemical and biological threat detection. An approach is shown to achieve a narrow-band bolometric detector whose response can be tailored to both a desired peak wavelength and bandwidth. The approach will enable the design of an array of detectors meeting the requirements for chemical ...

Physical Sciences, Inc. (PSI) proposes to demonstrate environmentally benign, low cost biological agent simulant particles that mimic the infrared, scatter, fluorescence and atomic absorption spectra of bacillus subtilis (BG), Erwinia herbicola (EH), and the MS2 Bacteriophage (MS2). These stimulant particles will be composed of materials that are commonly available foods or nutritional supplement ...
