For a sinusoidal plane wave, the wavefronts are planes perpendicular to the direction of propagation, that move in that direction together with the wave.For a sinusoidal spherical wave, the wavefronts are spherical surfaces that expand with it.If the speed of propagation is different at different points of a wavefront, the … 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 single focal … 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 … See more A wavefront sensor is a device which measures the wavefront aberration in a coherent signal to describe the optical quality or lack thereof in an optical system.
