In this proposal, AlphaSense, Inc. proposes to develop an innovative real time probe for online monitoring of plastic bonded explosive manufacturing process. Key innovations of the proposed sensor probe include: a) the use of a white light interferometer (WLI) to form real time images of the particles for accurate particle size measurements, and b) the use of quartz crystal microbalance (QCM) base ...

Mid-infrared (MWIR, wavelength ~10 micron) imaging has significant importance in military surveillance and target recognition, since human body radiation peaks in MWIR. The GaSb/InAs type-II Strained Layer Superlattice (SLS) MWIR detector has been under intensive investigation recently. While much progress has been made to enhance wavelength coverage, one of the few remaining issues has been its r ...

Low light level infrared imaging has significant importance in military surveillance and target recognition. The proposed broadband low-light-level nano-BiCMOS camera covers visible and near infrared bands from 400 nm to 1,550 nm wavelengths. With a proven nano-technology, the proposed nano-BiCMOS photo-detector solves this long-standing tradeoff between quantum efficiency and dark current by in- ...

This project will demonstrate the feasibility of using an array of wireless, passive, microwave acoustic sensors and accompanying interrogator system to monitor temperature and pressure in harsh environments encountered within a turboshaft rotorcraft engine. The proposed sensor technology is based on langasite piezoelectric crystals and stable nanostructured thin film electrodes, and will enable ...

Superior high-temperature performance requirements for highly stressed rotating components of the compressor section in advanced Army turboshaft engines cannot be met by the existing materials and require sophisticated materials solution concepts. The objective of this SBIR program is to develop a reinforced high temperature titanium material system for impeller applications in advanced Army turbo ...

The military has a great need for very small, heavy-fuel (diesel or JP-8) engines for a wide variety of applications (e.g. small, unmanned air and ground vehicles, and power generation). Likewise the commercial small engine market (lawn tools, chainsaws, and model aircraft) can benefit from engines that burn heavy and alternative fuels while producing reduced emissions. However, there are numero ...
