We present a photomixing based continuous wave terahertz single pixel imaging system with quasi instantaneous amplitude and phase detection, allowing us to scan a terahertz image at 1 THz with 0.45 million measurement points in less than 8 min, which is as fast as previously demonstrated at lower frequencies (0.3 THz).
