Bilinear wavefront transformation

Journal of the Optical Society of America A, 2009
Truncated 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.

Wavefronts and reflection groups

Russian Mathematical Surveys, 1988
The author surveys in detail a new method of classifying the typical singularities occurring in problems on wave front sets and reflection groups. This method builds on the study of generating families of functions for given systems of rays and makes it possible to classify all generic singularities in three-dimensional problems on envelopes of systems

The wavefront and delta -wavefront algorithms: a comparative study

[1991 Proceedings] Tenth Annual International Phoenix Conference on Computers and Communications, 2002
The author studies and compares, using rigorous analytical models, the performances of two algorithms, wavefront and delta -wavefront, suitable for processing an important class of recursive queries, the partially-instantiated transitive closure ones. Such a study reveals, among other findings, that the performance of these algorithms individually as ...

Ptychographic wavefront cameras

Optics Letters
We introduce a snapshot wavefront camera capable of reconstructing the complex field of an object with near quantum-limited accuracy. This system incorporates a diffraction grating at the entrance aperture and an array of cameras positioned to align with the grating orders, capturing the field with varying impulse responses.
