Zusammenfassung: | The invention provides non-interference coded aperture correlation holography based on a scattering point spread function, and belongs to the field of computational optical imaging. Based on the randomness of a coding phase mask, the coding phase mask is regarded as a thin scattering medium, and a speckle correlation model of scattering imaging is introduced. Experiment cost and tedious operation caused by using a pinhole are avoided, a light path structure is simplified, a scattering point spread function is solved in a deconvolution mode, and the recording process can be completed only by using a reference object and all objects in the same plane.
本发明提出一种基于散射点扩散函数的无干涉编码孔径相关全息术,属于计算光学成像领域。基于编码相位掩膜的随机性,将其视为薄散射介质,引入散射成像的散斑相关模型。避免使用针孔带来的实验成本和繁琐操作,简化光路结构,通过反卷积的方式解出散射点扩散函数,仅用同一平面的参考物体和全部物体就能完成记录过程。 |
