Modeling classical wavefront sensors
WebShack-Hartmann wavefront sensors' limitations are related to the microlenses: first, the spatial resolution is determined by the size and number of the microlenses (limited to 100 … WebWavefront sensors are instruments that retrieve phase f(r) from wavefront-encoded intensity measurements. For incoherent light, direct wavefront sensing is not possible, …
