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 frequency (otherwise the phase is not well defined). Wavefronts usually move with time. For waves … Visa mer Optical systems can be described with Maxwell's equations, and linear propagating waves such as sound or electron beams have similar wave equations. However, given the above simplifications, Visa mer Methods utilizing wavefront measurements or predictions can be considered an advanced approach to lens optics, where a single focal distance may not exist due to lens thickness or … Visa mer • Huygens-Fresnel principle • Wavefront sensor • Adaptive optics • Deformable mirror Visa mer • LightPipes – Free Unix wavefront propagation software Visa mer 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.

If a wavefront is converging, we must replace v in Formula 3 with a positive number. Curvature and radius of curvature. From a geometrical standpoint, u, ƒ, and v are the radii of curvature of spherical surfaces.
