"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

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.

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.
