Fig. 2: Principle of time-resolved coherent correlation imaging.
From: Coherent correlation imaging for resolving fluctuating states of matter

Top, sequence of camera frames showing Fourier-space coherent scattering patterns. Coherent correlation imaging classifies scattering frames by their underlying domain state, as indicated by the colours. Bottom, real-space images reconstructed from an informed average of same-state frames. Scale bar, 500 nm.
