Abstract
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 camera is applied to acquire multiframe full-field holograms. We use a temporal frequency spectrum analysis algorithm 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 discussed. The typical objects of microlenses and biology cells are reconstructed well with 100-frame holograms for illustration.
