Some ground crews for aircrafts are exposed to ambient noise levels up to 150 dB SPL: at these levels, conduction of sound through tissues is significant and may be responsible for hearing loss. Protecting the ear canal with earplugs and earmuffs cannotprevent damage caused by tissue-conducted sound. Our research partners at University of Illinois at Urbana-Champaign, experts in bioacoustics and ...

The development and implementation of new damage morphology models for concrete materials is critical to understanding their dynamic behavior during severe shock loading environments. Current constitutive models of conventional strength concretes do not accurately represent the behavioral characteristics of new ultra-high strength concretes because of differences in damage mechanisms during failur ...

We propose a three-dimensional imaging approach based on digital holography. Our approach is based on frequency diversity using a single chirped pulse instead of a train of pulses with different frequencies. Our approach promises to mitigate most of the issues limiting the performance of current methods and offer additional enabling capabilities that will improve target identification and tracking ...

This Phase II STTR project will continue the research and development of a simultaneous multi-species sensor system for scramjets flight test instrumentation. The sensor system is based on modulation-frequency multiplexing to combine several laser wavelengths and using a single two-color photodiode detector to collect the laser signals along the same optical path. High-sensitivity detection of c ...

Target tracking and aimpoint maintenance are critical functions within a laser directed energy system. Traditionally, the optical sensor is a conventional camera viewing an actively illuminated target. In the absence of turbulence, it is still difficult to point the laser weapon to a specific hit spot when there are no features in the required direction. Further, atmospheric turbulence scintillate ...

We will develop hybrid wave propagation approach that implements FFT and EMA (Efficient Matrix Algorithms) propagators in a fashion that is transparent to the user but insures the highest efficiency and accuracy for a given propagation problem. We will develop rules to decide which propagation approach is ideal for a given situation. The propagation algorithms will be coded in Vulkan/CUDA and C++ ...

This effort joins the MEMS-based deformable mirror technology available from AgilOptics, a New Mexico small business, with the aero-optics technology of the University of Notre Dame to develop an Aero-optics Simulator. This simulator will develop a library of aero-optics patterns to simulate atmospheric distortions for test and evaluation of military or commercial beam control systems.

This contract develops and expands on the technology for micromachining silicon deformable mirrors as a result of work in Stanford research laboratories over the last 5 years. The commerical and military applications of this technology will be exploitedand specific uses will be investigated. Hardware specific to applications will be prepared and evaluated for a few selected uses.The optics indus ...

Future power conditioning, control electronics and directed energy weapons will require significant energy storage for a wide range of power applications. Systems will depend on capacitors to deliver high current and high voltage under repetition. In order to find practical embodiment on mobile platforms, significant advances in compact power sources will be required. In response this need, TP ...

In this proposal, Bluecom Systems proposes to develop a framework in designing and manufacturing smart materials that can be used as adaptive radiating structures to operate at different frequencies, with different radiation patterns, and achieve polarization diversity. The solution proposed, based on optically pixilated Silicon or GaAs surfaces, can be used as reflective surfaces for reconfigurab ...
