Abstract

Since cameras are too slow for shot-to-shot acquisition, pump-probe microscopy was limited to single-point detection. We demonstrate widefield pump-probe images spanning 100×100 μm2 using an all-optical lock-in camera based on off-axis holography. We use it to study exciton diffusion in perovskites around 100 diffraction-limited spots.
