Quick detection of Chemical/Biological (CB) agents in the field can provide critical reconnaissance and contamination avoidance. CB agents pose a serious threat to both civilian and military sectors, and present techniques rely on dangerous collection methods, active measurement through external infrared (IR) sources, and/or are time-consuming. EPIR proposes to provide critically needed improvemen ...

The primary goal of this proposed work is to develop a long wave infrared (LWIR) colloidal quantum dot (CQD)-based focal plane array (FPA) in order to significantly reduce the cost of LWIR hyperspectral imagers. In order to realize this goal, it will first be necessary to successfully fabricate and demonstrate the performance of novel LWIR HgTe CQD detector arrays. This will be accomplished thro ...

Current bolometers are broadband detectors and tend to absorb broad IR spectrum for thermal imaging. A key issue with these systems is the lack of sensitivity of the sensors in target detection due to blackbody radiation limit. As a result, one of the many important applications such as low concentration chemical detection cannot be performed. A solution to this problem is to employ cryogenic syst ...

To meet the critical security needs of the Department of Homeland Security and others, we propose two methods for providing a secure root of trust for mobile devices. One method is designed to integrate as easily into existing systems, while the other requires deeper integration but provides correspondingly stronger security. The keys to our work are practicality and integration: practicality to e ...

In the proposed effort, we will leverage this extensive experience and capabilities to realize a frequency agile mmW radiometer that can cover the range of DC-110 GHz and can be scaled to DC-200 GHz under Phase II. Ours is a photonic system that multiplies and up-coverts a low-frequency reference signal onto an optical carrier (laser) using EO modulation, then uses the modulation sidebands to inj ...
