Analysis of the wavefront reconstruction error of the spot location algorithms for the Shack–Hartmann wavefront sensor

, 2020
. Spot location algorithms greatly influence the wavefront measurement error of the Shack–Hartmann wavefront sensor. Based on numerical simulations and experiments, we compare the wavefront reconstruction error of several spot location algorithms under ...

Absolute calibration of a Shack-Hartmann wavefront sensor for measurements of wavefronts

OPTO, 2019
A high-quality flat wave front is usually used to calibrate the Shach-Hartmann wave-front sensors. The article discusses the possibility of calibrating sensors with spherical wave fronts.
