Effects of different scattering components in speckle autocorrelation imaging

Various methods of imaging through scattering media suffer a rapid degradation in image quality as medium thickness increases. To address this issue, based on speckle autocorrelation imaging we designed a double-layer diffuser experiment to study the effects of different scattering components on imaging. The results show that both singly scattered light and doubly scattered light can transmit information. However, the difference in memory effect range leads to diverse abilities in information extraction, thereby affecting image recovery. This study may provide insights into the mechanisms of information transmission within thick scattering media and methods to extract information from multiply scattered light to reconstruct images.
