Far-field terahertz electric-field imaging using a polarization image sensor

This work focuses on a far-field terahertz (THz) imaging technic. This one is based on two-dimensional electro-optical sampling (2D-EOS) where the temporal and spatial distribution of the THz electric can be reconstructed using a polarization image sensor. As we demonstrate in this work, compared to previous 2D-EOS demonstrations, the introduction of the polarization image sensor (PIS) greatly simplifies the imaging configuration. This is advantageous for the development of THz electric field imaging as well as for far-field hyperspectral THz imaging.
