Abstract: According to the scalar diffraction theory of light, the process of generating conjugated light by digital holography has been simulated in this paper. By using the conjugated light, the disturbance of scattering media is eliminated and the object covered by scattering media is imaged clearly. The imaging process in actual application is analyzed and discussed. Imaging effects caused by different particle sizes ofscattering medium and different depths of medium are simulated. In addition, the feasibility of realtime imaging by using CCD and spatial light modulator is also discussed.

Key words: digital holography, imaging, scattering media
