Autocorrelation is the correlation of a signal (beam of lights) with a likeness between observed functions in the form of time lag between the split laser beams. It is mathematical method for finding repeating patterns, like the existence a periodicity in a signal concealed by noise, or identifying the missing frequencies in a signal through its harmonic frequencies. It is used in signal processing for analyzing functions or series of values.
- Autocorrelation analysis is used in fluorescence correlation spectroscopy.
- Autocorrelation is the measurement of optical spectra and the measurement of short- duration light pulses (micrometer) produced by lasers.
- Autocorrelation is used to analyze dynamic light scattering data
- Autocorrelation of a signal can be analyzed in terms of the diffusion of the particles. Because of this we can determine viscosity of fluids and calculate particle sizes.
- In signal processing, autocorrelation can give information about repeating events like tempo or pulsar frequencies.
