Abstract
Multi-pixel terahertz (THz) detection based on the electro-optic principle is highly interesting for fast THz imaging. In the past, a CCD camera was used to measure the THz-induced-birefringence in an electro-optic crystal [1]. Due to the relatively weak birefringence, small modulation signals have to be detected on a large optical background. High THz field amplitudes are required to achieve an acceptable signal-to-noise ratio (SNR).
