In this Phase II SBIR effort we will dramatically reduce the size, weight, and power requirements of a passive millimeter wave imaging system based on optical upconversion. To this end, we will integrate custom silicon-germanium low noise amplifiers that have been designed to efficiently couple with our high performance lithium niobate upconversion modules. In Phase I we analyzed the design requ ...

ABSTRACT:We propose to develop and demonstrate component technologies, interfaces, and software necessary to build a prototype Short Wave Infrared (SWIR) projection system with high dynamic range and fast frame rates. More specifically, final hardware deliverables for this project include three (3) tested hybrid modules that integrate a 1024x1024 24-micron pitch SWIR LED emitter array with a match ...

Advance the TRL level of highly-loaded rate-augmented multi-pulse reduced-signature propellant solid propulsion system nozzle technologies selected in Phase I by developing desigh architectures and a credible materials data base required to establish accurate analytical design models and verifying design/materials performance through sub-scale and full-diameter prototype motor tests.

ABSTRACT:Emergence and feasibility for flexible body-worn electronics and particularly medical patches requires high performance electronics capability.The problem is that these new technologies must have flexible and conformal physical formats and conventional electronic components are not in any way flexible. In the CLAS Phase I program, a new flexible high-performance manufacturing and material ...

As infrared (IR) electo-optical sensors improve in both availability and quality a strong need exists to have comparable improvements in the performance of military obscurants within the IR band. Conventional approaches for creating effective IR obscurants have relied primarily on shaped metal particles with high aspect ratios (e.g. rods, flakes).

In this SBIR program, AlphaSense, Inc. teamed with the Center for Non-destructive Evaluations at Iowa State University to develop a compact, low cost handheld sensor for non-destructive material case depth verification. In phase I, we have proven the feasibility of using an alternating current potential drop (ACPD) sensor for non-destructive measurements of case depth. Phase II will be focusing on ...

ABSTRACT: Optical control of RF-signal transmission presents an attractive avenue for processing and transmitting RF information using various optical components, as opposed to electronic control, where metallic wires/cables are required. On a macroscopic scale, optical fibers offer low transmission losses, and hence are suitable for the distribution of control signals over long distances for lar ...

The overall objective of the proposed effort is to develop an improved ultrasonic consolidation (UC) process for metal matrix composites (MMCs). The Phase I effort demonstrated the feasibility of using a fiber-matrix unit cell finite element analysis to study the thermal and acoustic softening that occurs during UC. The analyses completed in Phase I highlighted the need for uniform prepreg mater ...

ABSTRACT: High-performance computing (HPC) programmers and domain experts, such as those in the Air Force's research divisions, develop solvers for a wide variety of application areas such as modeling next generation aircraft and weapons designs and advanced image processing analysis. When developing software for HPC systems, the programmer should not spend the majority of their time optimiz ...

In this program, we propose a radio frequency (RF) direction finding sensor for low probability of intercept (LPI) RF radar system. This sensor consists of a dielectric lenses focusing system and an innovative focus plane detector array (FPDA) developed by Spectrum Magnetics, LLC (SM). The focusing system project the RF signal onto its focus plane. A novel FPDA based on emerging spintronic and met ...
