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.

Keywords: space-time chaos, the largest Lyapunov exponent, transverse correlation function, nematic liquid crystal, interference method.
