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 ... For modest departures from perfection (i.e., aberrations which cause a ...

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 ...
