(a) Schematic representation of the setup used to measure time-resolved polarization, strain and structural changes simultaneously, with examples of fits to different q and angular regions of the azimuthally integrated diffraction patterns. (b) Lattice strain ɛhkl, from diffraction peak shifts for individual reflections with the scattering vector parallel to the electric field vector, calculated as a function of unipolar field cycling frequency.
