WebA wave front is defined as a surface of constant phase. Thus, the notion of a wave front implies one type of coherence—a lateral phase coherence across the wave front. A beam … Webwavefront would appear on the grid versus that of the one to be measured. This calculation would also provide the local slopes, or first derivative (angle), at which the wavefront intersected the surface behind each aperture of the grid. Shack and Pratt improved on Hartmann’s idea by using microlenses to focus the incident wavefront
