Abstract:

A terahertz THz wave imaging system using photoconductive antennas as an emitter and detector has been constructed and the focussing characteristics of the beam near the sample position has been investigated. By using this system, the images of photoexcited carrier distribution in silicon have been obtained with spatial resolution of 2.5 mm by measuring the transmission of the focused THz beams.
