Abstract :
We developed a compact and portable THz spectrometer based on millimeter-wave backward wave oscillators combined with frequency multipliers. The instrument operates in frequency range 0.1-1 THz, providing for spectral resolution of 1-10 MHz and dynamic range of at least three orders of magnitude. The system consumes less than 200 W of electrical power and does not require water cooling. Dimensions of the instrument are 70 cm x 40 cm x 35 cm and the weight is less than 40 kg.
