Autocorrelators

Minioptic Technology, Inc (Minioptic Technology)

Opticala Autocorrelators are devices for measuring the intensity or field autocorrelation function of light, mostly used for determining the pulse width of picosecond or femtosecond pulses, to which an electronic apparatus such as oscillascope would be too slow. The basic principle of operation of an autocorrelator for a pulse width measurement is to check the correlation of the temporal pulse trace with itself.
