SpletPhase Diversity (PD) is an algorithm for the reconstruction of a wavefront using image data from two planes symmetrically placed about the plane containing the wavefront. We … SpletWe compare phase diversity and curvature wavefront sensing. Besides having completely different reconstruction algorithms, the two methods measure data in different domains: phase diversity very near to the focal plane, and curvature wavefront sensing far from the focal plane in quasi-pupil planes, which enable real-time computation of the ...
