We theoretically analyzed our scheme and performed the experiment by scanning the object placed in between two ground glass diffusers. The image of the object is retrieved by collecting the amplitudes at the modulation frequency of all the cross-spectra. Our method is non-invasive, easy-to-implement, and can work for both static and dynamic media.5 pagesen-USCreative Commons Attribution 4.0 International (CC BY 4.0)https://creativecommons.org/licenses/by/4.0/deed.enCross-spectrumDetectorsFrequency modulationImagingMeasurement by laser beamMedianon-invasiveScatteringTurbid mediaUltrafast opticsText
