"WebHistory of Wavefront Technology. Wavefront technology was originally developed for use in astronomy. In the 1900s, an astrophysicist named Johannes Hartmann devised a method of measuring the ray aberrations of mirrors and lenses. The Hartmann test used a metal disk in which regularly spaced holes had been drilled. " - Ray and wavefront

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. WebHuygens Principle, also known as the Huygens–Fresnel principle, highlights the following wave propagation behaviour: Secondary sources form wavelets similar to the primary source. At any given time, the common tangent on the wavelets in the forward direction gives the new wavefront. The wavefront is the sum of the spherical wavelets.
