WebMATLAB toolbox to estimate wavefronts from Shack-Hartmann (SHWFS) images. This toolbox implements the modal-based wavefront reconstruction method described in Section 1.3.2 of [1]. It also contains code to generate and plot Zernike polynomials as defined by Noll [2]. Main Features automatic calibration from a given SHWFS reference image WebFeb 20, 2024 · The new wavefront is a line tangent to all of the wavelets. Figure 27.2. 2 shows how Huygens’s principle is applied. A wavefront is the long edge that moves, for example, the crest or the trough. Each point on the wavefront emits a semicircular wave that moves at the propagation speed v.
