Noun
wavefront (plural wavefronts)
(physics) An imaginary surface passing through points of a medium oscillating in phase.
A complex, aberrated wavefront profile may be curve-fitted with Zernike polynomials to yield a set of fitting coefficients that individually represent different types of aberrations. Source: Internet
A long slit of infinitesimal width which is illuminated by light diffracts the light into a series of circular waves and the wavefront which emerges from the slit is a cylindrical wave of uniform intensity. Source: Internet
In a retroreflector an electromagnetic wavefront is reflected back along a vector that is parallel to but opposite in direction from the wave's source. Source: Internet
The engineering of such high frequency direction finding systems for operation on ships presented severe technical problems, mainly due to the effects of the superstructure on the wavefront of arriving radio signals. Source: Internet
If an otherwise perfect wavefront is "aberrated" by piston and tilt, it will still form a perfect, aberration-free image, only shifted to a different position. Source: Internet
Nodes in all the different directions are explored uniformly, appearing as a more-or-less circular wavefront as Dijkstra's algorithm uses a heuristic identically equal to 0. Let the node at which we are starting be called the initial node. Source: Internet
