AOLI (Adaptive Optics Lucky Imager) is a state-of-art instrument thatcombines adaptive optics (AO) and lucky imaging (LI) with the objective ofobtaining diffraction limited images in visible wavelength at mid- and big-sizeground-based telescopes. The key innovation of AOLI is the development and useof the new TP3-WFS (Two Pupil Plane Positions Wavefront Sensor). The TP3-WFS,working in visible band, represents an advance over classical wavefront sensorssuch as the Shack-Hartmann WFS (SH-WFS) because it can theoretically usefainter natural reference stars, which would ultimately provide better skycoverages to AO instruments using this newer sensor. This paper describes thesoftware, algorithms and procedures that enabled AOLI to become the firstastronomical instrument performing real-time adaptive optics corrections in atelescope with this new type of WFS, including the first control-relatedresults at the William Herschel Telescope (WHT).
