WebThe autocorrelation function is always the largest at the origin R f ( 0) ≥ R f ( τ) and it is symmetric R f ( − τ) = R f ( τ). So as one can expect, the highest similarity is found with no … WebAutocollimation. Autocollimation is an optical setup where a collimated beam (of parallel light rays) leaves an optical system and is reflected back into the same system by a plane …
WebThe measure of the decay time of the fluorescence autocorrelation function gives the particles' diffusion time in the excitation volume, and from an a priori knowledge of the diffusion coefficient we can estimate the excitation volume. WebThe compressed pulse has ,50 mJ of energy and a duration of 60 fs. The au- tocorrelation in a 100-mm b-barium borate crystal is shown in Fig. 2 along with a fit assuming Gaussian …
