We demonstrate an all-optoelectronic, continuous-wave (CW) terahertz spectroscopy and imaging system based on temperature-tunable diode lasers. Time-domain waveforms are acquired for each pixel, and the use of multiple frequencies enables spectroscopic image display modes. We discuss the separation of the amplitude and phase parameters, and compare the accessible information with that obtained using pulsed terahertz systems.
