Spectral Sciences, Inc. proposes an innovative ultrafast spectroradiometer for transient thermal event detection at surfaces in order to provide contamination avoidance and mitigation. The proposed system combines an adaptive, software programmable spectral filter with advanced signal processing algorithms to identify contaminates based on transient thermal excitation of a sample. The adaptive s ...

Quantitative Raman spectroscopy offers a means of estimating concentrations of protein variants. The Raman spectrum can be a fingerprint of an individual molecule and features unique to functional groups. In conjunction with robust data analysis such as principal component analysis (PCA), chemometric assessment of a sample can be performed. As an optical technique, this approach can yield high-thr ...

Physical Sciences Inc. (PSI) proposes to develop a software tool that is capable of fusing disparate data sources including hyperspectral standoff sensor data products, weather information, and point sensor data generated from a deployed network of sensors. The proposed software suite will be based on an algorithm that will compute the threat type, spatial and temporal concentration profiles as we ...

Leveraging on Agiltron industry leading development of optical systems and the PI experience with FTIR spectrometer design, we propose to develop a new class of compact monolithic Fourier-transform spectrometers for the long-wave (7.5-13 m) infrared optical range. The proposed solution is based on creating a spatial interferogram with a pair of a calomel Wollaston prisms and digitizing it with an ...

Biological agents pose high threats, because they are invisible and odorless and a relatively small amount can infect a large population when released in a densely populated area. For the same reasons, assuring safety after cleaning decontaminated sites can be challenging. Currently available technologies require considerable labor, and results typically cannot be obtained before 24 V 48 hours up ...

The threat of military and terrorist deployment of chemical weapons has increased alarmingly in recent years. A universal decontamination system is required for safe and effective neutralization of standard and thickened chemical warfare agents (G, V, and H). The system must be non-toxic, non-corrosive, and non-hazardous to equipment and personnel. For effective implementation, the system must be ...

The ability to detect minute quantities of toxic biological substance s will provide the ability to quickly assess a situation so that an a ppropriate response to exposure can be orchestrated. Not only will t he development of this technology be important in toxic agent warfare detection, the biological sensors would be pertinent in commercial ap plications such as process control and point-of-ca ...

Recent developments in the world political arena have led to The need for miniaturized instrumentation for rapid characterization of micro-organisms and toxins to protect military and civilian personnel against biological weapons and to allow timely administration of prophylactics. Considerable effort is currently underway to develop polymerase chain reaction (PCR) assays with automated samp ...

Leveraging on Agiltron industry leading development of optical MEMS devices and the PI experience with FTIR spectrometer design, we propose to develop a new class of high performance compact and rugged FTIR spectrometers for the LWIR optical range. The design is based on the MEMS lamellar mirror technique. Although this approach is not new, it has not yet been efficiently applied to LWIR, and per ...

Longwave infrared (LWIR, 8-12µm) focal plane arrays (FPAs) play an important role in hyperspectral chemical and biological (CB) sensing and spectral imaging. Existing thermal detectors are unable to meet the high sensitivity and fast response requirements of many hyperspectral chemical and biological sensing applications. FPAs based on photon excited electron generation process can fulfill the sp ...
