Wavefront guided ablation

American Journal of Ophthalmology, 2001
A DAPTIVE OPTICS WAS FIRST SUGGESTED IN 1953 BY astronomer Horace Babcock to remove the blurring effects of turbulence in the atmosphere on telescopic images of stars.1 The U.S. Defense Department later invested heavily in the development of adaptive optics technology to improve the effectiveness of laser weapons as part of its Star Wars Program.

Multilcolor Wavefront Reconstruction

Applied Optics, 1967
Two and three primary colors derived from an He-Ne gas laser and an argon gas laser were employed in recording and reconstructing holograms. For the tricolor case it is possible to reconstruct a three-dimensional multicolor image which possesses almost all the natural hues of the original object.

Wavefront scatter and wavefront healing

The Journal of the Acoustical Society of America, 2001
While acoustic scattering is essentially a time domain phenomenon, studies of scattering from objects in water, and from boundaries, have often concentrated on time-independent/cw descriptions. There are, however, critical aspects of the scattering problem which become evident only in the time domain.

Wavefront reconstruction using smartphone based wavefront sensors

SPIE Proceedings, 2015
Smartphone camera system has the capability of being integrated into powerful field-sensing tools, capturing data and sharing these data with computing servers or cloud experts. The purpose of this work is to implement a wavefront sensor based on the smartphone platform, which has many potential applications in thin-films and bio-related sensing areas.
