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, 1967Two 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, 2001While 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, 2015Smartphone 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.

Wavefront processing of radio-frequency wavefront data
Proceedings of the IEEE, 1984A class of special-purpose processors is described. These processors are for use in holographic imaging systems that utilize electromagnetic waves with radio frequencies. The systems, which operate in very nearly real time, consist of arrays of receiving antennas with a receiver at each antenna.

Bilinear wavefront transformation
Journal of the Optical Society of America A, 2009Truncated expansions such as Zernike polynomials provide a powerful approach for describing wavefront data. However, many simple calculations with data in this form can require significant computational effort. Important examples include recentering, renormalizing, and translating the wavefront data.

A reference wavefront for wavefront sensing instruments
Workshop on Optical Fabrication and Testing, 1986A reference light source (RLS) was designed to allow the measurement and removal of system wavefront errors in wavefront sensing instruments. The wavefront of the RLS is produced by collimating and re-focussing the output of a laser diode onto a 1 micron pinhole aperture.
