WebWavefronts play an important role in wave optics.Note, however, that wavefronts are generally defined only for monochromatic waves, since they are based on the concept of the phase, which is not clearly defined for polychromatic waves. In such cases, one can still consider the wavefronts for particular optical frequency components.. The wave vector is … WebWavefront sensing is an important part of adaptive optics system, which plays a key role in the fields of ground-based telescopes, laser transmission in atmosphere, wireless optical …
