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 ...

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., ...

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 ...
