Presents readers with the basic science, technology, and
applications for every type of adaptive lens
An adaptive lens is a lens whose shape has been changed to a different focal length
by an external stimulus such as pressure, electric field, magnetic field, or temperature.
Introduction to Adaptive Lenses is the first book ever to address all of the fundamental
operation principles, device characteristics, and potential applications of various types
of adaptive lenses.
This comprehensive book covers basic material properties, device structures and
performance, image processing and zooming, optical communications, and
biomedical
imaging. Readers will find homework problems and solutions included at the end
of each chapter—and based on the described device structures, they will have the
knowledge to fabricate adaptive lenses for practical applications or develop new
adaptive devices or concepts for advanced investigation.
Introduction to Adaptive Lenses includes chapters on:
•
Optical lenses
•
Elastomeric membrane lenses
•
Electro-wetting lenses
•
Dielectrophoretic lenses
•
Mechanical-wetting lenses
•
Liquid crystal lenses
This is an important reference for optical engineers, research scientists, graduate
students, and undergraduate seniors.
