In this work we propose and experimentally verify multi-pixel interdigitated photoconductive devices for broadband THz polarization control [1] and imaging. To create arbitrary linear polarisation states, an array of horizontally and vertically polarized THz radiation dipoles was produced using a patterned photoconductive antenna, as illustrated in Fig. 1(a) and 1(b). Here a 2×2 grid of pixels, with the electrodes in each pixel arranged orthogonally to those in the adjacent pixels.
