Abstract

The present invention discloses a speckle correlation imaging method and device based on the Wirtinger Flow algorithm, wherein the method includes: S1, acquiring a target speckle image, performing autocorrelation Fu Lie transform to obtain the target power spectrum; S2, establish the cost function of the target image and the target power spectrum through the Wirtinger Flow algorithm, optimize the cost function through the optimization algorithm and solve the optimal solution of the cost function, and reconstruct the target image according to the optimal solution . This method can improve the robustness of the target reconstruction process to measurement noise and system distortion, does not require any prior information of the target, and improves the quality of the reconstructed target.

Description

technical field [0001] The invention relates to the technical field of anti-scattering imaging, in particular to a speckle correlation imaging method and device based on the Wirtinger Flow algorithm. Background technique [0002] The light waves carrying target information will scatter when they pass through strong scattering media such as biological tissue, smoke, egg film, etc., so that the target information carried by the light waves will be re-encoded, and what the detector receives is a random speckle image, which cannot Identify the outlines and details of objects. [0003] Speckle correlation imaging technology is a technology developed based on the inherent optical memory effect of strong scattering media, which can perform imaging in the presence of strong scattering media on the transmission path. The optical memory effect was first proposed by Israeli scientist I. Freund et al., that is, after the light wave passes through the scattering medium, when the inciden...
