The goal of this STTR effort is to design a portable, multimodal, non-contact imaging system for burn depth diagnosis and tracking of wound healing. UC and Vanderbilt University will build upon our previous efforts demonstrated via porcine model studies to combine results from structural B-mode optical coherence tomography (OCT) images and functional data (pulse speckle imaging- PSI) to classify d ...

An experimental method is proposed to enable time-resolved measurements of both gas and particle velocities in explosions containing particles for munitions research. The approach involves novel processing methods for two-dimensional images that allow discrimination of the image content based on particle size. This allows an image containing a poly-dispersed distribution of particles to be decompo ...

Additive manufacturing (AM) technologies covering a broad range of technologies and processes have been under continuous and accelerating development since the 80s. While there are still fundamental hurdles such as low production rates and small sizes, AM holds tremendous promise in terms of revolutionizing manufacturing. Recent trends include direct-printing and incorporating sensors and electr ...

Current scene projection hardware is challenged to simultaneously meet the requirements for high peak temperature (> 2000K), high resolution (2Kx2K), response time < 4 ms, cryogenic and temporally uniform photon flux. MEMS, Resistor arrays, liquid cr...

Laboratory investigations have suggested that acoustically or vibrationally inducing motion in buried targets can aid in improving target detectability through a characteristic response related to differential target motion. This gain is realized by adding an additional degree of freedom, modulation due to motion in the GPR return signal, to use as a discriminating feature. The AKELA team is propo ...

Based on our success in developing the world first commercial high energy femtosecond fiber laser system and our leading proprietary technology development in ultrashort pulsed fiber laser material processing, PolarOnyx proposes, for the first time, a compact high energy fiber laser based smart wound healing tool to meet with the requirement of this DHP solicitation. It includes a high energy fs f ...

The aerothermal environment for hypersonic flight vehicles is severe and can generate extremely high material temperatures. These high-temperature environments can cause intense localized heating, which may result in local pockets and/or structural instabilities, especially at vehicle leading-edge regions, and may lead to disruptions that affect vehicle performance. The aerothermal environment may ...

We propose to investigate, in collaboration with the Massachusetts General Hospital Voice Center and Altec, Inc., the application of surface electromyography (sEMG) to assessing cognitive workload, strain, and overload. Specifically, sEMG sensors placed on the face and neck will detect emotional/motor responses to workload strain. The proposed effort will build on the substantial sEMG experience o ...

The US Air Force has noted a need for a tool for broadband (300 nm2m) measurement of optical propagation properties such as absorption and scattering coefficients. A simple and inexpensive generic tool for extracting these properties from samples would be beneficial to many areas of both DoD and general scientific and industrial research. The present proposal seeks to develop a commercial instrume ...

During the last two decades, vertical-external-cavity surface-emitting lasers (VECSELs) have emerged as excellent high-power laser sources that combine diode-pumping, broad-pump tolerance, wavelength selectivity, narrow linewidth, broad tunability, high beam quality, compactness, and efficiency into one attractive package. These characteristics make them an ideal candidate for use as more economic ...
