Centroid error due to non-uniform lenslet illumination in the Shack-Hartmann wavefront sensor

Images formed by individual Shack-Hartmann wavefront sensor lenslets are displaced proportionally to the average wavefront slope over their aperture. This principle fails when the lenslet illumination is non-uniform. Here we demonstrate that the resulting error is proportional to the linear componen...
