Based on recurrence plot (RP) of chaotic time series, this paper develops the definition of cross recurrence plot (CRP) and the average length of close orbits, which reflects the similarity of two time series and is used to classify time series.

Coherent Hole-burning is a new theory that combines the optical hole-burning and atomic coherence.

The results indicate that atomic coherence of the four-level atomic system will be abated when the laser field linewidth is build up and laser field linewidth inhibits electromagnetically induced absorption.

We show the control of optical bistability and multistability via the atomic coherence induced by the microwave field in the presence of the antirotating wave coupling.

The key of the algorithm is to point out the dependability of data by choosing coherence maps.

In this paper,a method to record rainbow hologram through coherent image converted by liquid crystal light valve (LCLV) is proposed.

Based on the theory of deformation decorrelation of the active ground fissures,we mainly investigates the positioning method of active ground fissures by analyzing the pseudo-coherence map of adaptively filtered differential interferogram.
