Abstract
Applying super-resolution imaging techniques to recover object behind scattering media can obtain more information. Our previous work stochastic optical scattering localization imaging breaks the diffraction-limit via object blinking. Here, we proposed a more practical method using speckle fluctuation to achieve super-resolution imaging. The speckle fluctuation in the illumination part cause object fluctuating, resulting in a series of speckle fluctuation frames in the camera. By analyzing the high order cumulants of deconvolution frames, not only the noise artifacts are suppressed but also resolution enhanced by a factor of square root of N , where N is the cumulant order.
