In previous chapters and in appendix A we discuss the means by which ray paths are traced through an optical system and how the numerical values of ... For modest departures from perfection (i.e., ...

With a rigorous foundation of electromagnetic-wave propagation, the authors develop geometric optics, aberrations and optical design with many applications. A detailed analysis of diffraction in ...

The use of deformable mirrors to correct unwanted optical aberrations ... Adaptive optics relies on wave-front sensors to measure aberrations in light coming into a telescope, camera, or similar ...

Real physical waves, such as light beams, spread, diffract, scatter and interfere in complex and chaotic ways. An intriguing consequence of this is are 'singular' features of waves, such as optical ...

Wavefront sensors measure the aberrations of an optical wavefront. They are common in adaptive optics systems, lens testing, and ophthalmology. A wavefront is the collection of points having the same ...

In the center, pulse compression is demonstrated as the metasurface adjusts the phase of the optical wave, enabling tighter ... objectives can provide aberration-free and high-resolution imaging, ...

using a variety of optical distortions, that light-correcting light is naturally produced by passing them all into a nonlinear crystal, even for extremely complicated forms of the aberrations that ...
