In optics, various autocorrelation functions can be experimentally realized. The field autocorrelation may be used to calculate the spectrum of a source of light, while the intensity autocorrelation and the interferometric autocorrelation are commonly used to estimate the duration of ultrashort pulses produced by … See more To a complex electric field $${\displaystyle E(t)}$$ corresponds an intensity $${\displaystyle I(t)= E(t) ^{2}}$$ and an intensity autocorrelation function defined by See more The optical transfer function T(w) of an optical system is given by the autocorrelation of its pupil function f(x,y): See more As a combination of both previous cases, a nonlinear crystal can be used to generate the second harmonic at the output of a Michelson interferometer, in a collinear geometry.

A nonlinear interaction is used for obtaining a signal that depends on the pulse overlap, and the pulse duration can be retrieved from that signal. ray white rdWebOptics: Half-wave plateInstructor: Shaoul EzekielView the complete course: http://ocw.mit.edu/RES-6-006S08License: Creative Commons BY-NC-SAMore information ... ray white real estate albany
