Abstract

Pump-probe microscopy was limited to single-point detection because cameras are too slow for shot-to-shot demodulation. We use off-axis holography to create an all-optical lock-in camera, obtaining pump-probe images spanning 100×100 μm². We use it to study exciton diffusion in perovskites around 100 diffraction-limited spots.
