Abstract

This thesis investigates holographic and non-holographic techniques for quantitative phase retrieval and three-dimensional (3D) reconstruction. First, a digital holography framework combined with the transport of intensity equation (DH+TIE) is studied for phase reconstruction through theoretical analysis and numerical simulations. A point-cloud-based digital holography simulation and reconstruction method is further investigated. To suppress interlayer crosstalk in multilayer imaging, a multi-wavelength digital holography (MWDH) method is proposed to separate optical fields from different axial layers and improve reconstruction accuracy. Finally, practical applications in 3D fingerprint imaging are explored, including DH+TIE-based fingerprint topography reconstruction and a non-interferometric ray-tracing framework for recovering fingerprint height information from detector-plane intensity distributions. The results demonstrate the feasibility and potential of the proposed methods for quantitative phase retrieval, multilayer holographic reconstruction, and optical biometric imaging.
