Optics autocorrelation

WebJan 23, 2024 · Imaging through scattering media remains a big challenge in optics while the single-shot non-invasive speckle autocorrelation technique (SAT) is well-known as a promising way to handle it.... 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. In this case, the signal recorded by a slow detector is See more • Autocorrelator • Convolution • Degree of coherence See more
