UV Spectral Imaging for Gas ID and Material ID

光谱成像是一种新兴的技术，为目标识别（ID），地形分类，气体检测和类似的应用提供了很大的希望。这一领域的大部分工作都是在用于侦察的电磁频谱的传统部分，即可见光和红外线上进行的。 光谱的UV部分通常被打折，因为在短波长处的光水平降低。 然而，有足够的光从0.3-0.4微米进行光谱测量和成像，并提高灵敏度的气体和其他材料。这个光谱范围有缺点：散射是一个严重的问题，空间分辨率降低。 这一努力将把用于气体检测的紫外光谱成像的实验室仪器转移到现场，以测试真实的情况数据采集并量化信号中的噪声水平。 此外，还将进行材料紫外线光谱成像的实验室测试。 有强大的理论基础相信这将是一种新的，有用的技术，用于新兴材料检测。 还将使用新的芯片探索使用紫外线照片作为图像数据。 结合现场测试，替代芯片技术提供了一个机会，创建一个校准系统，可用于实时成像检测有毒气体羽流使用便携式传感器。 应用包括烟囱和火山羽流。 部分现场测试将通过马诺阿的夏威夷大学进行协调。

Spectral imaging is an emerging technology that offers great promise for target identification (ID), terrain classification, gas detection, and similar applications. Most of the work in this area has been done in the traditional portions of the EM spectrum used for reconnaissance, the visible and infrared. The UV portion of the spectrum is typically discounted because of the decreasing light levels at short wavelengths. There is, however, sufficient light from 0.3-0.4 microns to conduct spectral measurements and imaging, and enhanced sensitivity to gases and other materials. There are downsides to this spectral range: scattering is a significant problem, and spatial resolution is degraded. This effort would move laboratory instrumentation for UV spectral imaging for gas detection into the field to test real situation data acquisition and quantify the level of noise in the signal. In addition, a laboratory test of UV spectral imaging of materials will be undertaken. There are strong theoretical grounds for believing this will be a new, useful technology for emerging materials detection. The use of UV photographs as image data will also be explored using new chips. In combination with the field test, the alternative chip technology offers an opportunity to create a calibrated system that could be used for real-time imaging detection of noxious gas plumes using a portable sensor. Applications include smoke stacks and volcanic plumes. Part of the field test will be coordinated through the University of Hawaii, Manoa.
