Abstract
The velocity of a diffuser which moves very slowly has been measured on the basis of photon temporal autocorrelation. The experimental results show that the correlation time is proportional to the reverse of the velocity, which is quite in agreement on the theoretical prediction. In order to gain insight into the abilities and limitation of the measurement system, the nonideal effects in photon counting correlation are analysed in theory.
