We revive a cross-platform focal-plane wavefront sensing and controlalgorithm originally released in 1980 and show that it can provide significantcontrast improvements over conventional control methods on coronagraphicinstruments. Its simplicity makes it applicable to various coronagraph modelsand we demonstrate it on a classical Lyot coronagraph and a phase-apodizedpupil Lyot coronagraph, both in simulation and in laboratory experiments.Surprisingly, it had been forgotten for decades, but we present its unbeatableadvantages considering the increase in computational power in the last 40years. We consider it a major game changer in the planning for future,space-based high-contrast imaging missions and recommend it be intensivelyrevisited by all readers.
