  Light passing through scattering media will be strongly scattered and
diffused into complex speckle pattern, which however contains almost all the
spatial information and color information of the objects. Although various
technologies have been proposed to realize color imaging through the scattering
media, current technologies are still complex with long sequence of measurement
for each imaging pixel or spectral point spread functions of optical system.
Here we theoretically prove the spatial averaging of triple correlation
technique can be used to retrieve the Fourier phase of object, and
experimentally demonstrate it can be applied in color imaging through
scattering media. Compared to other phase retrieval techniques, the phase
retrieval with triple correlation technique can retain the orientation
information of objects, and can composite color image without rotation
operation. Furthermore, our approach has the potential of realizing spectral
imaging through scattering media.
