We recently started to investigate how liquid-crystal on silicon (LCOS)spatial light modulator (SLM) would perform as programmable focal-plane phasemask (FPM) coronagraphs. Such "adaptive coronagraphs" could potentially helpadapt to observing conditions, but also tackle specific science cases (e.g.binary stars). Active FPMs may play a role in the context of segmentedtelescope pupils, or to implement synchronous coherent differential imaging(CDI). We present a status update on this work, notably early broadbandcontrast performance results using our new Swiss Wideband Active Testbed forHigh-contrast imaging (SWATCHi) facility. Finally, we unveil the upcomingnear-infrared PLACID instrument, the Programmable Liquid-crystal AdaptiveCoronagraphic Imager for the 4-m DAG observatory in Turkey, with a first lightplanned for the end of the year 2022.
