Abstract

High resolution high power W-band (92-100 GHz) spectroscopic system was constructed and experimentally tested. The system is based upon two parabolic mirrors, high power high resolution continuous wave tunable THz source and unique THz detector. The spectrometer is fully computerized. The quasi-optical system was design to transfer maximum beam power with minimum aberrations and minimum system internal reflections. Stray refractions were eliminated by placing absorber blocks around the system. Spectral resolution of tens of kHz is achievable. The system was designed to measure transmission function of sample using wide collimated beam of 75 mm diameter in order to simulate THz imaging situation.
