Correlation method for measuring the largest Lyapunov exponent in optical fieldsKeywords: space-time chaos , the largest Lyapunov exponent , transverse correlation function , nematic liquid crystal , interference method Abstract: We propose an analog interference method for measuring the largest Lyapunov exponent for the optical fields generated by scattering objects and media. The method is further developed to make a device for high-speed real-time measurements of transverse correlation function of the optical fields.
