Off-axis holograms recorded with a CCD camera are numerically reconstructed with a
calculation of scalar diffraction in the Fresnel approximation. We show that the zero order of …

In this day of digitalization, you can work within the technology of optics without having to
fully understand the science behind it. However, for those who wish to master the science …

PURPOSE: To compare changes in the corneal wavefront aberrations after photorefractive
keratectomy and laser in situ keratomileusis. METHODS: In a prospective randomized study …

The detailed displacement data provided by finite element analysis (FEA) tools must be
translated into forms acceptable by most optical ray tracing tools (CODE V specifically). A …

PURPOSE: To investigate whether corneal wavefront aberrations vary with aging.
METHODS: One hundred two eyes of 102 normal subjects were evaluated with …

OBJECTIVE: To assess the relation between magnitude of refractive correction and changes
in higher order wavefront aberrations of the cornea after laser in situ keratomileusis …

An image-based wavefront sensing and control algorithm for the James Webb Space
Telescope (JWST) is presented. The algorithm heritage is discussed in addition to …

The nonlinear response and strong coupling of control channels in micromachined
membrane deformable mirror (MMDM) devices make it difficult for one to control the MMDM …

purpose. To assess the relationship between apparent accommodation in pseudophakic
eyes, multifocal corneal effects, and wavefront aberrations of the cornea. methods. In 102 …

Techniques for retrieving the phase of an optical field typically depend on assumptions
about the amplitude of the field in a desired plane, usually a pupil plane. We describe an …
