Paper Abstract
In this report, we demonstrate characteristics and parameters of a coherence-gated Shack-Hartmann wavefront sensor
(CG/SH-WFS) that is capable of measuring depth-resolved wavefront aberrations. A technique of dynamic centroiding is
applied to CG/SH-WFS images and its precision is evaluated. The performance of the CG/SH-WFS system is compared
with a commercial SH-WFS measuring a reflective surface. Real-time wavefront measurements from a scattering sample
are also presented. The experiments demonstrate that the performance of CG/SH-WFS can replace conventional SHWFS
and also provide its unique advantages.
