In recent years, the need for highly reliable, durable and non-intrusive systems for monitoring the health condition of naval structures becomes more and more recognized. Of particular importance is the condition based maintenance of Navy rotating machinery (motors, generators, pumps, gear systems, etc.). Such Structural Health Monitoring (SHM) systems should be able to detect failures in their ea ...

W-band millimeter waves have a number of important applications, including directed energy and, more recently, 5G FR2 network development. Reliable measurements of electric fields in the W-Band, while critical to the development of these applications, have proven challenging. This proposal addresses the development of an accurate, traceable, cost effective W-band RF field strength detector. The so ...

Nanoscale, material sensitive, imaging techniques are critical for progress in many disciplines as we learn to master science and technology at the smallest dimensions — on the nanometer to atomic-scale. However, progress in both science and technology is becoming increasingly limited by the constraints of current imaging techniques and metrologies. Fortunately, by combining coherent extreme UV ...

Suppression of noise from aircraft is a vital NASA goal, especially important for the vision of Urban Air Mobility. Small urban aircraft may utilize Distributed Electric Propulsion along with advanced structural and electric motor/storage technologies to achieve the necessary flight capability. However, these aircraft utilize propellers or fans to achieve the necessary thrust, with attendant commu ...

Through the execution of our Phase 1 effort, Nutronics, Inc. and Montana State University developed an improved means to optimize the Pellizzarri cost functional for coherent imaging using digital holography. Our algorithm developed during the Phase 1 effort accelerates convergence times by a factor of 20-40 for the majority of scenarios evaluated. Our proposed Phase 2 effort has a two-fold focus: ...

This Small Business Technology Transfer Phase I project will develop ultradense, low-power plasmonic integration components and devices for on-chip manipulation and processing of optical signals. Both passive and active components will be studied. Detailed performance predictions will be obtained through finite element modeling (FEM) of the harmonic Maxwell’s equations. The FEM provides detai ...

The proposed Phase II supports completion of the RINGS science missions on ISS using SVGS as real-time sensor for the EMFF maneuver. During Phase I, SVGS-based navigation of RINGS was developed and tested on a 3DOF ground-based platform, and mechanical and electrical integration of RINGS with the free-flying robotic platforms on ISS (Astrobee) was designed in detail. SVGS was deployed and tested o ...

Due to huge levels of computing parallelism and higher performance per watt, comuting accelerators are crucial for increasing HPC efficiency. This is economically significant for small and medium size manufacturing companies (SMMs) and essential for transition to Exascale computing. However, due to high procurement costs, in-house maintenance of an accelerated HPC cluster is prohibitive for many ...

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 ...

Locating objects that vibrate is a way to discern potential threats and locate targets. However, current vibrometry technology typically measures only the global vibration of target and cannot create an extended spatial measurement of the vibration profile of the target. These solutions cannot identify what the target is, nor can they locate potential weak spots on the target, because they lack sp ...
