Nonlinear Spline Wavefront Reconstruction with a Shack-Hartmann Sensor through Sensorless Adaptive Optics Techniques

Adaptive optics (AO) is a technology widely used in astronomy, microscopy and lithography that reduces the degrading effect of wavefront aberrations on optical systems, by cancelling out the induced wavefront phase profile. A critical part in AO is the wavefront reconstruction, in which an estimate of the phase profile is made from sensor...
