Abstract :
Spectroscopic terahertz imaging with the InGaAs-based bow-tie diode as room temperature THz detector was proposed. Images were recorded in transmission mode from 0.5 THz up to 2.5 THz applying an optically-pumped molecular THz laser. The content of compounds in test samples was studied and discriminated from the spectroscopic imaging results along with Fourier spectroscopy data.
