RXT determines very small angular displacements by using the diffraction intensity of individual crystals. (a) The first and last frames of the time series, showing the (104) alumina powder ring in the vertical direction. (b) Each of the powder ring intensity frames is radially integrated (horizontally) and plotted versus time. (c) Trajectories are extracted to obtain the angle versus time for a single particle. (d) The trajectory is then tracked to quantify the angular motion.
