Abstract:

We propose to develop a frequency domain terahertz dual beam spectrometry system tunable from 0.2 to 3 THz with resolution <5 MHz. The turn-key bench top spectrometer will employ a long path length (greater than 1M) dual beam path, with two pair of transmitters and receivers. The system can be operated in two modes: reference normalization and differential frequency. In the reference normalization mode, one transmitter-receiver pair will probe a sample path and the other a reference path, and both will be swept with the same frequency simultaneously in order normalize spectral artifacts and improve signal to noise. In the frequency differential mode, the two transmitter and receiver pairs will probe the same path, but at two different frequencies, in order to measure an instantaneous ratio. The system will be utilized to measure THz spectra of bacteria and other bioweapon simulants as a powder suspension in air within a long path length chamber. Explosive spectra will be measured in transmission and reflection. The data will be utilized to program neural network spectral recognition software, and provide operational parameters for long range (>25M) field detection systems and interferometric imagers to be configured from this technology in phase III.
