George P. Eppeldauer, Vyacheslav B. Podobedov
An InSb working standard radiometer, first calibrated at NIST in 1999 against a cryogenic bolometer, was recently calibrated against a newly developed low-NEP pyroelectric transfer standard detector. The pyroelectric transfer standard, which can operate at

Submillimeter and THz Detection of Chemical-Warfare Agents in Air

Vyacheslav B. Podobedov, R J. Lavrich, T M. Korter, Gerald T. Fraser, David F. Plusquellic, A C. Samuels
Experimental measurements and theoretical calculations were performed to assess the potential for using continuous-wave submillimeter and THz (far-infrared) linear-absorption spectroscopies to detect chemical-warfare agents in air at ambient temperatures
