Direct demodulation for alternative Shack-Hartmann alignment

Combining Fourier demodulation with curvature sensing

The Shack-Hartmann wavefront sensor is a widely-used device to measure the light wavefront. Cur- rently, the sensor is used as a gradient sensor, which is achieved by placing the microlens array in the plane conjugate to the deformable mirror and the aberration. The resulting spo ...
