In this book, computational optical phase imaging techniques are presented along with Matlab codes that allow the reader to run their own simulations and gain a thorough understanding of the current state-of-the-art. The book focuses on modern applications of computational optical phase imaging in engineering measurements and biomedical imaging. Additionally, it discusses the future of computational optical phase imaging, especially in terms of system miniaturization and deep learning-based phase retrieval.

This book illustrates a number of numerical and computational methods for phase recovery in order to reconstruct images with high fidelity that are hard to obtain with traditional brightness contrast imaging. It not only gives readers a theoretical and numerical background of some of the most advanced experimental and algorithmic methods, such as interferometry, coherent diffraction imaging (CDI), and transport of intensity equations (TIE), but it also allows readers to experiment with several MATLAB simulations to retrieve phase information from samples. The conditions for successful imaging are examined in light of reconstructed accuracy, computing cost and computing time. The book also goes over a few contemporary applications as well as recent AI-based discoveries.
