摘要

This book highlights the formation of holographic images using modulated apertures across eleven comprehensive chapters. It begins with a summary of basic Fourier transformations used to compute diffraction patterns of well-known objects. The fundamentals of holography are outlined, followed by an investigation of Fourier holographic images obtained using argon plasma. This book also explores Fourier holographic images using modulated Hamming apertures and discusses the use of scanning holography with linear and quadratic apertures. Advanced topics include the processing and segmentation of cancerous mammographic images using improved Fourier holograms, and the detailed study of Fourier holographic imaging of modulated apertures. The recognition of colored objects and the computation of the point spread function (PSF) using operator algebra in Gaussian beam illumination are also covered. This book concludes with a discussion on pattern recognition and information processing. This book serves as an essential resource for researchers and students interested in the advanced techniques and applications of holographic imaging.
