Webb20 apr. 2015 · Wavefronts reconstructed from measured gradients are composed of a straightforward integration of the measured data, plus a correction term that disappears when there are no measurement errors, and it is shown that for rectangular regions, the correct solution is not a periodic one, but one expressed with Fourier cosine series. WebbVergences describe the curvature of wavefronts. Geometric optics considers the propagation of spherical wavefronts - i.e. wavefronts emanating from point sources. A good two-dimensional analogy is the waves one observes on the surface of a pond after throwing a stone into the water. A ‘vergence’ physically represents the curvature of a ...

This is the curvature which the lens adds to the wavefront. Power is measured in dioptres, D, and is given by the formula: , where f equals the focal length of the lens, in meters.
