Feasibility of THz Remote Sensing for DoD Applications
Abstract
This project was designed to identify applications of THz technology of potential interest to the DoD and to provide a technical introduction for DARPA personnel to the underlying scientific and technical issues. The final report begins with a discussion of the physics which governs the interactions between radiation and matter in the THz, with emphasis on the differences between low pressure gases, atmospheric pressure gases, and solids. Atmospheric propagation is considered as an example. Two specific applications were developed in more detail. The first is a concept for a point detector of gases, which is based on the absolute specificity of rotational spectra in the THz. The second is a remote detection scheme which makes use of THz/IR double resonance. The former is based on well understood science and the risks for the development of-such a program lie in the trade-offs against alternative solutions as a function of scenario. Although the details of application scenarios are not known to the authors, it is highly likely that some of them are very favorable. The latter is a high risk/high payoff scheme whose eventual utility depends not only upon application scenario, but also on currently unknown scientific parameters.
