Add to ORKGWe present new results with the Asymmetric Pupil vector-Apodizing Phase Plate (APvAPP), which combines coronagraphy and wavefront sensing to enable a 100% science duty cycle. We show on-sky results at SCExAO with a non-linear, model-based wavefront sensing algorithm improving the raw contrast by a factor of 2 at 2-4 lambda/D. We also report on the first on-sky demonstration of spatial Linear Dark Field Control with the APvAPP. Together, these algorithms improve the control speed, raw contrast gain and allow more modes to be corrected. Finally, we discuss the path towards coherent differential imaging with the APvAPP
