Imaging with a multichannel terahertz time-domain spectroscopy system at 1030 nm excitation wavelength
Abstract
We present Terahertz imaging with a 1D multichannel time-domain spectroscopy system (TDS) which operates with a photoconductive array of 15 detection channels excited by a 1030 nm femtosecond fiber laser. The emitter and detector are photoconductive antennas based on InGaAs/InAlAs multi-layer heterostructures (MLHS). The simultaneous measurement of 15 THz pulses with a pixel pitch of 1 mm increases the measurement speed by factor 15.
