Imaging diagnostics systems are very important to aid the understanding of core and edge confinement in 3D helical magnetic devices. In this paper we consider recent developments in optical “coherence imaging” interferometric systems that open new diagnostic capabilities for next generation devices, with particular focus on Motional Stark Effect (MSE) imaging. We present preliminary results obtained using a hybrid spatio-temporal heterodyne snapshot imaging polarimeter-interferometer for motional Stark effect imaging of the q-profile in the TEXTOR tokamak.
