WebWe can use interferometric methods, however these may be limited to the use of coherent light (like a laser). Shack-Hartmann wavefront sensors can work in incoherent and even broad-band light. A Shack-Hartmann wavefront sensor consists of an array of micro-lenses focusing portions of an incoming wavefront onto position-sensitive detectors. WebThe basic principle underlying the method is that a wavefront can be evolved by repeated application of local ray tracing from a set of points lying on the wavefront surface. Thus, for some given time step δt, a new wavefront is deﬁned by the end points of the rays traced from the old wavefront, as illustrated schematically in Fig. 28.
