Wavefront curvature sensor — A wavefront curvature sensor is a device for measuring the aberrations of an optical wavefront. Like a Shack Hartmann sensor it uses an array of small lenses (or lenslets) to focus the wavefront into an array of spots. Unlike the Shack Hartmann,… … Wikipedia
Wavefront — In optics and physics, a wavefront is the locus (a line, or, in a wave propagating in 3 dimensions, a surface) of points having the same phase. Since infrared, optical, x ray and gamma ray frequencies are so high, the temporal component of… … Wikipedia
Wavefront sensor — A wavefront sensor is a device for measuring the aberrations of an optical wavefront. Although an amplitude splitting interferometer such as the Michelson interferometer could be called a wavefront sensor, the term is normally applied instruments … Wikipedia
