Abstract

To provide a non-interferometric, non-iterative complex amplitude reading method and apparatus that can detect complex amplitude information, including amplitude and phase, from a single diffraction image based on intensity images.SOLUTION: The non-interferometric, non-iterative complex amplitude reading method includes: diffracting a light beam including amplitude information and phase information to obtain a diffraction pattern of an intensity distribution; and constructing a diffraction intensity-complex amplitude model and training it based on a correlation among the diffraction pattern and the amplitude information and the phase information, and applying the trained model directly to new diffraction images to obtain amplitude information and phase information. The method can achieve detection of complex amplitude information, including amplitude and phase, from a single diffraction image, improve stability and accuracy of phase reading results, increase calculation speed, and simplify an optical system, and the method is suitable for applications in holographic storage, biomedical image processing, and microscopic imaging.SELECTED DRAWING: Figure 11
