Visualization of Terahertz radiation on silicon-based CCD and CMOS sensor at high resolution

Low frequency THz radiation is visualized by means of a charged-coupled device designed for optical frequencies and a CMOS sensor. This technological advance opens novel opportunities in THz imaging as it offers smallest pixel size and large chip size at low cost. Furthermore the sensor is insensitivity to background noise and is able to detect radiation of multiple spectral ranges from x-rays to THz. This is particularly beneficial for spatial overlap finding in two-color pump probe experiments.
