从复杂背景中的距离检测威胁是一种有价值的，通常是救命的实用程序。高光谱成像（HSI）允许在复杂的环境场景中检测威胁材料，其中感兴趣的目标通常浓度低，并且与干扰物和不同的基质共存。理想的HSI传感器能够在安全的距离内近实时地自动评估场景，以避免对操作员和设备造成伤害的风险。不幸的是，许多当前一代的HSI传感器具有阻碍有效处理这些情况的能力的限制。这些系统通常具有低效的区域搜索速率，不提供接近实时的测量，或者要求用户非常接近所讨论的材料。ChemImage传感器系统公司（CISS）开发了一种宽视场、便携式短波红外高光谱成像（SWIR HSI）传感器，称为VeroVision™ Threat Detector，能够在各种应用中检测远距离的威胁材料（即爆炸物、毒品）。便携式HSI传感器旨在以接近实时的速度分析复杂场景。该传感器利用短波红外吸收光谱，以提供从1到20+米的间隔距离的目标区域的分子鉴别。该传感器有一个定制开发的软件包，使操作员能够调整其光谱库，以纳入新的威胁材料或改变感兴趣的目标类型。本文将概述VeroVision，并讨论如何将其有效地应用于房间和车辆清理应用。
The detection of threats from a distance within a complex background is a valuable and often lifesaving utility. Hyperspectral Imaging (HSI) allows for the detection of threat materials in convoluted environmental scenes, where the target of interest is typically low in concentration and co-located with interferrants and varying substrates. The ideal HSI sensor is able to automatically assess scenes in near real-time and at a safe standoff distance to avoid risk of harm to the operator and equipment. Unfortunately, many current generation HSI sensors have limitations that hinder the ability to effectively handle these situations. These systems often have an inefficient area search rate, do not provide near real-time measurements, or require the user to be in close proximity to the material in question. ChemImage Sensor Systems (CISS) has developed a wide-field, portable shortwave infrared hyperspectral imaging (SWIR HSI) sensor called VeroVision™ Threat Detector capable of detecting threat materials (i.e. explosives, narcotics) at standoff distances for a variety of applications. The portable HSI sensor has been designed to analyze complex scenes at near real-time speeds. The sensor utilizes SWIR absorbance spectroscopy to provide molecular discrimination of the target area at standoff distances from 1 to 20+ meters. The sensor has a custom developed software package that provides the operator the ability to adapt its spectral library to incorporate new threat materials or change the type of target of interest. This paper will provide an overview of VeroVision as well as a discussion on how it may be effectively applied to room and vehicle clearing applications.
