中文摘要：

相位检索技术利用直接测量得到的强度分布恢复相位信息，从而重建波函数，是光学和图像处理中的重要研究领域。在研究了现有的基于强度传输方程的相位检索的基础上，建立了符合自然光条件下普通相机拍摄图像原理的光传播模型，设计了相应的数据采集光学平台系统，并推导了新模型下的相位检索方法。模拟和真实实验结果验证了相位检索方法的合理性和正确性。新方法的提出将传统的基于强度传输方程的相位检索算法的应用范围扩展到了全息显示等宏观领域。

英文摘要：

Phase retrieval technique using the directly measured intensity distribution to recover phase information and reconstruct the wave function is an important area of optics and image processing. Taking advantage of the existing phase retrieval based on transport equation of intensity,the light propagation model consistent with the principle of general camera images in natural light conditions is established, the corresponding optical data collection platform is designed and a phase retrieval method in this new model is derived. Real experimental results verify that this new phase retrieval method is reasonable and correct. The application of traditional phase retrieval algorithm on transport equation of intensity is extended to the holographic display and other macro-areas.
