Autocorrelation evaluation from clipped photon detection.
We present two new techniques for estimating the autocorrelation function, based on the measurement of the mean number of clipped photocounts and on the calculation of the second-order factorial moment of a series of clipped data. The first procedure has the advantage of simplicity, although it produces a poor signal-to-noise ratio. On the other hand, the second technique gives a very good signal-to-noise ratio, when compared with other known methods.
