3D imaging through a diffuser is a popular topic recently due to its extensive use, which is from earth observation to biomedical diagnosis. Although many methods have been proposed to realize this goal, such as holographic imaging and wavefront shaping, it is still complicated i.e. they require either a reference beam or sequential scanning to compensate the random phase. Here, we proposed a new verified approach without reference beam, just using a structured light illumination combined with time averaging technology to resolve the phase of the object. The result shows that this method is easy to get 3D image without speckle noise. Furthermore, it can also be used to detect the deformation of a hidden object and be extended to the biomedical imaging.
