Continuous wave spectroscopic terahertz imaging with InGaAs bow-tie diodes is demonstrated at room temperature. Spectra and images of plastic explosive simulators prepared from tartaric acid and sucrose are recorded within the frequency range of 0.585–2.52 THz. The bow-tie diode performance and implementation for real-time imaging applications are discussed.
