主　　题：fiber random laser speckle-correlated imaging scattering medium spatial coherence 

摘      要：Optical memory effect-based speckle-correlated technology has been developed for reconstructing hidden objectsfrom disordered speckle patterns,achieving imaging through scattering ***,the lighting efficiency and fieldof view of existing speckle-correlated imaging systems are ***,a near-infrared low spatial coherence fiberrandom laser illumination method is proposed to address the above *** the utilization of random Rayleighscattering within dispersion-shifted fibers to provide feedback,coupled with stimulated Raman scattering for amplification,a near-infrared fiber random laser exhibiting a high spectral density and extremely low spatial coherence is *** on the designed fiber random laser,speckle-correlated imaging through scattering layers is achieved,with highlighting efficiency and a large imaging field of *** work improves the performance of speckle-correlated imagingand enriches the research on imaging through scattering medium.
