英文摘要	Recovering information of an object hidden behind turbid media has a vast range of applications. People have been trying many ways to achieve this goal. In this paper, we use lensless Fourier transform digital holography and statistical average to retrieve object information from speckle field. The relationship between parameters of ground glass and peak signal-tonoise ratio of reconstructed image is explored by establishing a rotating ground glass interferometric imaging system. The light beam emitted from the laser is divided into two beams by the beam splitter. One beam passes through the rotating ground glass after being reflected by the object (i.e. object light), and the other beam passes through the reflector and convex lens as a reference light, and then interferes with the object light. Finally the interference speckle pattern is captured by a CCD camera. Experiment results show that there is an optimal solution between the rotation speed of ground glass and the peak signal-to-noise ratio of the reconstructed image.This method has the advantages of compact system construction, easy implementation and fast reconstruction, since it does not require phase correction, complex image processing, scanning object or wavefront shaping. © COPYRIGHT SPIE.
