http://wyant.optics.arizona.edu/zernikes/Zernikes.pdf The deviation of a wavefront in an optical system from a desired perfect planar wavefront is called the wavefront aberration. Wavefront aberrations are usually described as either a sampled image or a collection of two-dimensional polynomial terms. See more In physics, the wavefront of a time-varying wave field is the set (locus) of all points having the same phase. The term is generally meaningful only for fields that, at each point, vary sinusoidally in time with a single temporal … See more Methods utilizing wavefront measurements or predictions can be considered an advanced approach to lens optics, where a … See more • Huygens-Fresnel principle • Wavefront sensor • Adaptive optics • Deformable mirror See more • LightPipes – Free Unix wavefront propagation software See more Optical systems can be described with Maxwell's equations, and linear propagating waves such as sound or electron beams have similar wave equations.
