A Shack–Hartmann wavefront sensor is an optical detector used for measuring electromagnetic wavefronts. It is a wavefront sensor commonly used in adaptive optics systems and as a non-interferometric m
Shack–Hartmann system in clinical optics: Laser creates a virtual light source in the retina. The lenslet array creates spots in the sensor according to the wavefront coming out of the eye.
