Ingeometrical optics, light propagation is analyzed in terms of
light rays which define the path of propagation of light energy in
the limitofthe optical wavelength tending to zero. Many features
oflight propagation can be analyzed in terms ofrays,ofcourse,
subtle effects near foci, caustics or turning points would need an
analysis based on the wave natureoflight. Allofgeometric optics can
be derived from Fermat's principle which is an extremum principle.
The counterpart in classical mechanics is of course Hamilton's
principle. There is a very close analogy between mechanics
ofparticles and optics oflight rays. Much insight (and useful
results) can be obtained by analyzing these analogies. Asnoted by
H. Goldstein in his book Classical Mechanics (Addison Wesley,
Cambridge, MA, 1956), classical mechanics is only a geometrical
optics approximation to a wave theory! In this book we begin with
Fermat's principle and obtain the Lagrangian and Hamiltonian
pictures of ray propagation through various media. Given the
current interest and activity in optical fibers and optical
communication, analysis of light propagation in inhomogeneous media
is dealt with in great detail. The past decade has witnessed great
advances in adaptive optics and compensation for optical
aberrations. The formalism described herein can be used to
calculate aberrations ofoptical systems. Toward the end of the
book, we present application of the formalism to current research
problems. Of particular interest is the use of dynamic programming
techniques which can be used to handle variational/extremum
problems. This method has only recently been applied to
opticalproblems.
Ever since their invention in 1960, lasers have assumed tremendous
importance in the fields of science, engineering and technology
because of their use both in basic research and in various
technological applications. Lasers: Theory and Applications 2nd
Edition will provide a coherent presentation of the basic physics
behind the working of the laser along with some of their most
important applications. Numerical examples are scattered throughout
the book for helping the student gain a better appreciation of the
concepts and problems at the end of each chapter and provides the
student a better understanding of the basics and help in applying
the concepts to practical situations. This book serves as a text in
a course on lasers and their applications for students majoring in
various disciplines such as Physics, Chemistry and Electrical
Engineering.

This book describes the principles of image and video compression
techniques and introduces current and popular compression
standards, such as the MPEG series. Derivations of relevant
compression algorithms are developed in an easy-to-follow fashion.
Numerous examples are provided in each chapter to illustrate the
concepts. The book includes complementary software written in
MATLAB SIMULINK to give readers hands-on experience in using and
applying various video compression methods. Readers can enhance the
software by including their own algorithms.
This textbook provides engineering students with instruction on
processing signals encountered in speech, music, and wireless
communications using software or hardware by employing basic
mathematical methods. The book starts with an overview of signal
processing, introducing readers to the field. It goes on to give
instruction in converting continuous time signals into digital
signals and discusses various methods to process the digital
signals, such as filtering. The author uses MATLAB throughout as a
user-friendly software tool to perform various digital signal
processing algorithms and to simulate real-time systems. Readers
learn how to convert analog signals into digital signals; how to
process these signals using software or hardware; and how to write
algorithms to perform useful operations on the acquired signals
such as filtering, detecting digitally modulated signals,
correcting channel distortions, etc. Students are also shown how to
convert MATLAB codes into firmware codes. Further, students will be
able to apply the basic digital signal processing techniques in
their workplace. The book is based on the author's popular online
course at University of California, San Diego.

This textbook provides senior undergraduates studying modern optics
with a comprehensive account of optics and optical electronics. A
large number of solved and unsolved problems are included in the
book. The extensive coverage makes it valuable to postgraduates,
and also to optical engineers, as a source of basic design
information. The initial chapters cover the basic principles
involved in the propagation of electromagnetic waves. These are
followed by a description of diffraction and its application to
spatial frequency filtering and holography. Laser theory and the
various types of laser are covered, as well as the theory of
optical waveguides, fibre optics and integrated optics. The final
chapters cover electrooptics, acoustooptics, and nonlinear optical
effects.
A collection of problems in electromagnetics for the undergraduate
level, this book covers the basic as well as some applied aspects.
Apart from fundamental areas like electrostatics, magnetostatics,
wave propagation, reflection and refraction, the book also has
problems in magnetic circuits, metallic waveguides and dielectric
waveguides. Many of these problems have been evolved over the past
decade of teaching the course to undergraduate students.The
problems are at various levels of difficulty, starting from the
simplest. Some of the problems should help the reader in further
understanding the field and also in the application of the basic
understanding. Along with the problems solutions to all the
problems have been provided to help the reader to test his/her
understanding of the concepts.
Recent advances in the development of low-loss optical fibers have revolutionized the field of telecommunications, and fiber-based networks form a key part of international communications systems. This book introduces the physical principles of optical fibers, and details their use in sensor technology and modern optical communication systems. The authors begin by setting out the basic propagation characteristics of single mode and multimode optical fibers. In later chapters they cover optical sources, optical detectors, and fiber-optic communication system design. They also treat a wide variety of related topics such as doped fiber amplifiers, dispersion compensation, fiber sensors, and measurement techniques for the characterization of optical fibers. The book emphasizes physical and engineering aspects of the subject. It will be an ideal textbook for undergraduate or graduate students taking courses in optical fiber communications, photonics, or optoelectronics.
