Physical Sciences Inc. (PSI) proposes to develop a sensor system based on an innovative approach for liquid contaminant detection and identification on operationally-relevant surfaces. The proposed system will provide a sensitive (1 mg/m2 objective, 500 mg/m2 threshold), stand-off (

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 ...

Current CB garment systems such as Joint Services Lightweight Integrated Suit technology (JSLIST) and Joint Service Lightweight Integrated Suit Technology (JSLIST) Chemical Biological Coverall for combat vehicle crewmen (JC3) use a layer of absorptive carbon and selectively permeable membranes respectively offering protection against chemical and biological threats. It is not uncommon for garments ...

Mitigation and recovery from an attack with a chemical or biological agent remains an important challenge for the US Defense and Homeland Security. Solicitation topic CBD13-101 envisions a multifunctional sequestration coating that once applied to a contaminated surface will sequester the contaminating agent, disclose the location of agent contamination, detoxify the agent and be removable so as ...

Chemical warfare agents, such as nerve and mustard agents, pose serious threats to our soldiers and civilians. An efficient barrier coating which can sequester and deactivate chemical agents is urgently needed. We propose a broad spectrum responsive nanocomposite gel coating that can irreversibly sequester and deactivate a variety of chemical agents. Our base material is a fast curing gel modified ...

The ultimate goal is to develop coatings to self-seal or heal a textile material. Soldiers"personal safety is compromised when CB protective uniforms become torn. This project aims to achieve this objective by coating or laminating a shape memory elastomeric polymer composite thin film with CB protective and excellent self sealing capability to an existing soldier garment fabric material. The pot ...

In the event of an intentional or accidental release of ionizing radiation, it will be critical to have rapid triage assessment tools to evaluate the health of mission-critical personnel and to make effective use of available medical and emergency resources. However, assessment of whole body radiation dosage is challenging and established methods rely on visual manifestations, blood sampling and s ...

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 ...

Protein manufacturing is of paramount importance to chemical and biological defense applications. High-throughput protein purification is a critical need for rapidly scaling the target protein product. Existing purification methods primarly rely on synthetic-resin based chromatography, which is time-consuming, labor-intensive, expensive, and consequently, ill-suited for developing rapid countermea ...

Image processing methods have been studied and implemented for the vehicle classification over the past decades. The most dominant approach is the use of vehicle dimension, which requires complex processes of sensor calibration as the vehicle dimensions shown in the imagery are heavily dependent on the camera’s field of view. In general, video systems have physical disadvantages related to the ...
