Shack-Hartmann sensors are widely manufactured and sold by more than 10 companies worldwide. These wavefront sensors measure the gradient (first derivate) of the wavefront at a series of points across ...

Based on a Shack-Hartmann wavefront sensor, which detects the "ripples" of light waves reflected when a laser hits an object, the Complete Ophthalmic Analysis System from WaveFront Sciences, of ...

A 2023 investigation introduced a subaperture superposition technique for Shack–Hartmann sensors that robustly improves the signal-to-noise ratio when observing faint objects, facilitating more ...
