Hyperspectral Imaging Sensor with Real-Time Processor Performing Principle Components Analyses for Gas Detection.

摘要

Chemical warfare agents in the gas phase are a considerable threat from terrorists anywhere there are enemy forces on a battle field. The ability to detect, identify and determine the direction of propagation of such gases is of considerable interest to the armed forces. With support from the US Air Force and Navy, Pacific Advanced Technology has developed a small man portable hyperspectral imaging sensor with an embedded DSP processor for real time processing that is capable of remotely imaging gas plumes. Then, based upon their spectral signature the species and concentration levels can be determined. This system has been field tested at numerous places including White Mountain, CA, Edwards AFB, and Vandenberg AFB. Recently evaluation of the system for gas detection has been performed. This paper presents these results.
