文摘Digital holographic microscopy using multiframe full-field heterodyne technology is discussed in which two acousto-optic modulators are applied to generate low-frequency heterodyne interference and a high-speed cam- era is applied to acquire multiframe full-field holograms. We use a temporal frequency spectrum analysis algo- rithm to extract the object＇s information. The twin-image problem can be solved and the random noise can be significantly suppressed. The relationship between the frame number and the reconstruction accuracy is dis- cussed. The typical objects of microlenses and biology cells are reconstructed well with lO0-frame holograms for illustration.
