Image Processing Techniques for Deformed and Sparse Aperture Systems (Paperback)

This book explores advanced image processing techniques for systems with deformed and sparse apertures. Building on the author's recent research, this book is designed for graduate students and researchers in the fields of optical sciences and optical engineering.

The book begins with a unique investigation into aperture shapes inspired by coronavirus (COVID-19) imagery, followed by an analysis of cardiac-shaped apertures and their integration into confocal laser systems. Subsequent chapters look at the design and resolution analysis of heterogeneous apertures, including cascaded black-linear and linear-conic configurations, as well as hexagonal geometries.

The book also introduces the Straubel filter within circular apertures and its impact on confocal imaging performance. Later chapters revisit the coronavirus model in optical contexts and explore triangular aperture models applied to speckle photography. The final chapter presents a comprehensive study of Modulated Sparse Aperture Imaging Systems (MSAIS) and their effectiveness in enhancing speckle image quality.

With a blend of theoretical modeling, practical design, and application-driven insights, this book offers a valuable contribution to the evolving field of computational optics and aperture engineering.

Abdallah Mohamed Hamed graduated from Ain Shams University with a B.Sc. in Physics in 1973, achieving an excellent with Honors degree.  Subsequently, he earned an M.Sc. in Laser Optics from the same university in 1976. In 1978, he was awarded a scholarship in France, culminating in the acquisition of a Doctor of Science degree in 1985. The author is interested in speckle and holographic imaging, and confocal laser microscope. 

His scholarly contributions include 98 scientific publications, with 69 of these publications being indexed in Scopus. Moreover, he actively participates in international scientific organizations and serve as a reviewer for various scientific journals such as Opt. Eng., J. Modern Opt., Opt.&Laser Tech., and Opt. Communication. Since 2011, he has been an emeritus professor of Physics (optics and laser) at Ain Shams University.
