Abstract
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.
