This book aims to overcome traditional ray paradigm and provide an
analytical paradigm for Nonimaging Optics based on Field Theory. As
a second objective the authors address the connections between this
Field Theory of Nonimaging Optics with other radiative transfer
theories. The book introduce the Field Theory of Nonimaging Optics
as a new analytical paradigm, not statistical, to analyze problems
in the frame of nonimaging geometrical optics, with a formulation
based on field theory of irradiance vector D. This new paradigm
provides new principles and tools in the optical system design
methods, complementary to flowline method, overcoming the classical
ray paradigm. This new Field paradigm can be considered as a
generalization of ray paradigm and new accurate and faster
computation algorithms will be developed. In parallel way, the
advance in the knowledge of the principles of Field Theory of
Nonimaging Optics, has produced clear advances in the connection
between nonimaging optics and other apparently discontented
theories of radiation transfer. The irradiance vector D, can be
considered as macroscopic average of Poynting vector, with clear
connection with radiation pressure. Lorentz geometry techniques can
also be applied to study irradiance vector D. There are clear
thermodynamic connections between nonimaging concentrator and
Stefan-Boltzmann law of radiation. From this thermodynamic
connection, nonimaging optics and irradiance vector D can also be
studied from phase space point of view. This book is intended for
researchers, graduate students, academics, and professionals
looking to analyze, design and optimize optical systems.
This book provides a comprehensive look at the science, methods,
designs, and limitations of nonimaging optics. It begins with an
in-depth discussion on thermodynamically efficient optical designs
and how they improve the performance and cost effectiveness of
solar concentrating and illumination systems. It then moves into
limits to concentration, imaging devices and their limitations, and
the theory of furnaces and its applications to optical design.
Numerous design methods are discussed in detail followed by
chapters of estimating the performance of a nonimaging design and
pushing their limits of concentration. Exercises and worked
examples are included throughout.
