ERDC TN-EQT-10-1, Polarized Illuminator for Very-Near Infrared Imaging

ERDC TN-EQT-13-1 "Modeling RDX Reduction within Iron Bed Reactors"

PURPOSE: Iron has been used to reduce organic contaminants including high explosives (HE) such as Research Department Explosive (RDX). Work is ongoing at the U.S. Army Engineer Research and Development Center (ERDC) to develop guidelines for using iron bed reactors to remove RDX in surface water runoff from the impact areas of firing ranges. As part of this work, a mathematical model was develo...

A Broadband Laser Illuminator for Active Hyperspectral Imaging

We have been investigating the use of supercontinuum (SC) laser technology to provide active illumination for shortwave infrared (SWIR) hyperspectral sensors in order to extend their operational window into the night and heavy overcast periods. Unlike a lamp, light from a broadband laser illuminator (BLI) can propagate long distances through the atmosphere while maintaining its spatial coherenc...

Improving 3-D Imaging Breast Cancer Diagnosis Systems Using a New Method for Placement of Near-Infrared Sources and Detectors

The objective of this research was to improve 3-D imaging system by near-infrared light emission in breast tissue to achieve a more accurate diagnosis of tumor. The results of repeated experiments in this research have shown that with this imaging system, a more accurate diagnosis of abnormal area depends on the location of the sources and detectors. Therefore, an optimal location model has bee...

Evaluation of Reflection Optical Imaging Characteristics Using Fluorescence with Near Infrared Wavelength at Different Depths of Tissue Equivalent Phantom

A Solid-State Hyperspectral Imager for Real-time Standoff Explosives Detection using Shortwave Infrared Imaging

We present a new and innovative short-wave infrared (SWIR) hyperspectral imaging focal plane array (FPA) concept for bulk and trace standoff explosives detection. The proposed technology combines conventional uncooled InGaAs based SWIR imaging with the wavelength selectivity of a monolithically integrated solid-state Fabry-Perot interferometer. Each pixel of the array consists of a group of sub...
