Current continuous wave (CW) and pulse mid-wave infrared (MWIR) lasers have design and performance limitations that constrain their usability in some critical Air Force applications. There is an important need to create a new class of MWIR laser sources with less drawbacks and higher pulse energies and CW powers. The proposed work will demonstrate the technical feasibility of an innovative MWIR la ...

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++ ...

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 ...

Tau Technologies is teaming with Dr. David Voelz and his research group at New Mexico State University (NMSU) to propose “Vibration Imaging for the characterization of extended non-cooperative targets�, which employs dual-pulses in two different variations for vibration imaging in order to characterize non-cooperative targets at extended standoffs. One method is based on double-pulse ...

Efficient design, build, and test of an HEL system leverages modeling and simulation (M&S) to reduce cost and increase robustness. Designers use models to explore parameter variations and to estimate performance in conditions which cannot be tested due to physical or financial constraints. This provides significant savings in cost and time. Because live testing is so expensive, it is best used as ...

Wave-optics simulations are critical tools for analysis of laser directed energy systems. The primary method for conducting these simulations is to evaluate the Fresnel diffraction integral using the angular spectrum method based on the fast Fourier transform (FFT). While FFTs are considered computationally efficient, their use in the Fresnel integral results in difficult grid constraints includin ...

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 ...

Research is currently identifying new biochemical markers to help monitor cognition and stress in the human body and enhance human performance. Traditional biometric markers like heart rate, temperature, oxygen partial pressure, blood glucose, electrolyte concentration, and others have been correlated with cognition and stress states. However, the correlation is indirect. Molecular biomarkers with ...

The imaging vibrometer development will be based on a representative Directed Energy (DE) aperture assumed to be 30 cm. This effort will provide both DE and Combat IDentification (CID), modes for relative short range DE operations, and an ISR Combat IDentification (CID) mode for operation at extended range. A combination of analytic derivations and wave optics simulations will be used to define a ...
