Abstract
We present an all room-temperature cw THz spectrometer based on robust and low-cost dipole antennas without fragile interdigitated structures. Very accurate spectroscopic measurements and THz image with signal to noise ratio in amplitude exceeding 20 dB are presented. The overall cost, stability and speed of the presented system is superior to the one of the standard THz pulsed spectrometer based on a Ti: Sapphire laser.
