This book serves as a valuable resource for researchers and graduate students specializing in optical engineering and optical sciences. Comprising three distinct parts, it addresses fundamental aspects and practical applications of modulated apertures in microscopy. The first part delves into the fabrication of modulated apertures and the computation of impulse responses or point spread functions (PSFs). It offers essential insights into the foundational concepts of modulated aperture design. The second part focuses on the utilization of modulated apertures in speckle imaging, elucidating their significance and relevance in this context. This section provides a comprehensive understanding of the practical applications of modulated apertures in image formation. The third and final part explores the application of modulated apertures within the framework of a confocal scanning laser microscope. The objective here is to enhance microscope resolution and image contrast, contributing to the advancement of microscopy techniques. This book offers a concise and objective exploration of modulated apertures' fabrication, applications, and their potential to enhance microscopy. This book is a valuable reference for students and researchers seeking to deepen their knowledge in this specialized field.

This book deals concisely and coherently with various issues related to electroacoustic waves in piezoelectric layered composites. Starting with the basic linear equations and relations of electromagnet elasticity of homogeneous anisotropic piezoelectric media, the book considers the conditions for possible field or partial conjugation of physical and mechanical fields at the junction of two homogeneous media with geometrically homogeneous surfaces. The variety of electromechanical boundary conditions and the separation of plane and anti-plane fields of elastic deformation in homogeneous piezoelectric crystals are discussed. Then, the statements of the electroacoustic problem in piezo textures are studied and a layered piecewise-homogeneous piezoelectric waveguide is introduced, with non-acoustic contact between different piezoelectric layers. Non-acoustic contact between different piezoelectric layers can lead to the propagation of a hybrid of electroactive waves of plane and anti-plane elastic deformations. In the last part of the book, the problem of controlling electroacoustic waves in a waveguide is formulated. A method for solving problems of control of electroacoustic waves by non-contact surface action is proposed. .

The main aim of this book is to shine a spotlight on key experiments and their crucial importance for advancing our understanding of physics. Physics is an empirical science, and experiments have always been a driving force in the development of our understanding of nature. Facts matter. In that sense, the book attempts to be complementary to the many popularizations of theoretical physics, and to counterbalance the frequent emphasis there on more speculative ideas. Experimental physics is also an essential pillar in physics teaching, as well as helping broader audiences to better understand important concepts, particularly in challenging fields such as relativity or quantum physics, where our common sense intuition often fails. Readers are taken on an historical journey, starting with “Free Fall” and culminating in “Spooky Action at a Distance”. En route they will encounter many important branches of physics, whose main ideas and theoretical description will be given a more empirical meaning. At the end, the reader is invited to reflect on what could be exciting and important directions for fundamental physics. All readers with an undergraduate degree in physical sciences or engineering will enjoy and learn much from this stimulating and original text.

This book highlights the dynamical behavior of self-similar waves in asymmetric dual-core waveguides. The proposed dual-core waveguide consists of two closely spaced adjoining fibers in which one fiber is active and the other is passive. Due to the linear coupling between them, the dynamics of the wave propagating through the passive core can be controlled by manipulating the dynamics of the wave propagating in the active core. The optimal pulse compression or amplification of these waves as the length of the fiber tends to infinity is presented. The exact Mobius transform self-similar solutions that propagate through these waveguides self-similarly are subject to simple scaling rules. The book includes experiments conducted to corroborate the analytical predictions.
