WebHence, the significance of the wavefront is in that its form directly determines the quality of optical imaging in a telescope. Obviously, form of the wavefront and geometric properties … 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. 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. ears in the ocean
