Abstract

An adaptive technique for precise detection of the coherence function by intensity triple correlation is proposed. Adaptive change of the sampling interval and the calculation of differential phase in the transformed domain are used in this method so that the correct coherence function can be extracted even from fairly noisy data. Numerical analyses as well as experimental results show the effectiveness of the method.
