Exploring the Use of Event Based Imaging Sensors on Turbulence Characterisation and Adaptive Optics
Abstract
This grant was highly successful in spite of experimental problems associated with the pandemic. The teams has constructed a very useful model that can simulate the operation of event-based sensors in both Shack-Hartman and Holographic wavefront sensors. Simulations show that both would benefit significantly from using these sensors over current CCDs that use deterministic and full-frame readout. On the experimental side, they have clearly demonstrated the advantage of using event-based sensors for the spot image analysis in Shack-Hartmann wavefront sensors, with an increase in speeds of up to 2 orders of magnitude shown to be possible. Further study with more optimized and updated version of the sensor would be warranted. The PIs generated 2 high quality papers with 2 more expected.
