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. WebWavefronts are rays used in the graphical representation of wave behaviour. Wavefront is defined as the locus of all the points with a constant phase. A ray at any point on the wavefront is normal to the wavefront. The ray shows the direction of …
