Formanythousandsofyears,theSunwasouronlysourceoflight.Eventually,theabilitytocreate fire, and its by-product, light, led to a profound change in the way humans managed their time. Light is used to treat those with seasonal disorders. Lasers are now used in medical applications, suchasre-shapingourcorneas,cauterizingbloodvesselsandremovingtattoos.Lasersarealsoused in industrial applications, such as cutting metal, welding and sensing. New imaging technology permitsthecreationofflat-paneldisplays,nightvisiondevicesandautonomousproductinspection systems.Withsomanyapplicationsoflight,theneedforPhotonicstechnologyandinnovationwill most certainlygrow in the future, as new applicationsemerge tolight. A unique approach is taken in this book to present physical optics and their applications. This book covers the basic theoretical principles and industrialapplications of physical optics suitable for students, professionals and professors. Each chapter is presented in two parts: theoretical and practical.Thetheoreticalparthasadequatematerialtocoverthewholeaspectofthesubject.Inthe experimental part, students will apply the learned theoretical concepts in simple and advanced experimentalworks.Inthisway,studentswilllearnandgainpracticalhands-onexperienceinthe Photonics subjects. This will assist the students to apply theoretical knowledge to real-world applications.Thestep-by-stepapproachandtechnicalillustrationsinthisbookwillguidestudents througheachexperiment.Theexperimentalworkhasmorethanonecaseinmostofthechapters, and sometimeshave sub-cases. Thisbookiswritteninsimplelanguage,andgivesadequateinformationandinstructiontoenable students to achieve maximum comprehension. An effort has been made to use the international systemofunits(SI)throughoutthebook.Theorganizationofthechaptersisdesignedtoprovidea solid foundation for today’s physical optics students, and to upgrade their knowledge. Universal tools, devices and equipment, which are used throughout the experiments, are available in any Photonics,Physicsandmateriallabs.Thisbookaboundsintheoreticalandpracticalaids,andisan effectiveteachingtool,helpfultobothprofessorsandstudents.Simpleandadvancedsubjectsare presentedby an expert author, and somenew subjects appear for the first time inthis book. Care has been taken to label parts clearly, and to use colours in diagrams wherever it will aid understanding. Some figures are drawn in three dimensions, where applicable, for easy under- standing of the concepts. Colour pictures are used to clearly show parts in a device, system and experimental setup. Thebookisstructured into seven chapters. The book includesthe followingchapters: † Chapter1throughChapter5coverswaves, diffraction andinterference, the diffraction grating, interferometers andspectrometers. † Chapter6 covers laser technology. † Chapter7 covers laboratory safety. The book includes 222 figures, 19 tables and 22 experimental cases. The book was developed withgenerousinputfrommembersofthephotonicsindustry,researchscientists,andmembersfrom academia.
