Abstract
A technology of reconstructing a scattered image from turbid underwater is proposed, which is via stochastic resonance based on incoherent modulation instability in a noninstantaneous nonlinear medium. When intensity-dependent nonlinearity exceeds the threshold imposed by attenuation and scattering, instability preferentially reinforces the underlying signal modes at the expense of neighbor highly incoherent noise modes. Due to the directional energy transfer, noise-hidden signal images are effectively reconstructed with a cross-correlation gain high of 3.56. Results in turbid suspension demonstrated the wide applications of image detection in various dynamic scattering environments.
