Paper Abstract
Correlation wavefront sensing for extended objects requires both reference images for cross-correlation and centroiding parameters for measuring the shift in the correlation image. We present a method for optimising centroiding parameters demonstrated on a center of mass measurement of the correlation images. The process can be entirely automated and offloaded out of the adaptive optics system into a separate pipeline and so not interfere with the adaptive optics system. This means the method is implemented entirely in software, so can be added to any existing adaptive optics system which employs correlation wavefront sensors.
