Description	In ophthalmology, the term “wavefront sensing” is used in parallel with “aberrometry” and “spatially resolved refractometry.” Wavefront sensing originates from physics, especially from astronomy and from military applications of lasers. Aberrometry is a term in wide use in optics, as a means to describe the quality of optics. Spatially resolved refractometry was introduced to characterize nonhomogeneity of refractive properties of the eye. Measurement of spherical aberration of an eye was also proposed by means of a dioptometer—a telescopic system that can be focused on objects located at different distances from its entrance pupil. Interference, diffraction, and refraction phenomena are among those that can be used to determine the distortions of the wavefront. Light diffraction on gratings, diffraction on edges, shearing interferometry, and double-beam and triple-beam interferometry are the most known ones that use coherent light.
