Covers the fundamental principles behind optomechanical
design
This book emphasizes a practical, systems-level overview of
optomechanical engineering, showing throughout how the requirements
on the optical system flow down to those on the optomechanical
design. The author begins with an overview of optical engineering,
including optical fundamentals as well as the fabrication and
alignment of optical components such as lenses and
mirrors. The concepts of optomechanical engineering are then
applied to the design of optical systems, including the structural
design of mechanical and optical components, structural dynamics,
thermal design, and kinematic design.
Optomechanical Systems Engineering:
* Reviews the fundamental concepts of optical engineering as they
apply to optomechanical design
* Illustrates the fabrication and alignment requirements
typically found in an optical system
* Examines the elements of structural design from a mechanical,
optical, and vibrational viewpoint
* Develops the thermal management principles of temperature and
distortion control
* Describes the optomechanical requirements for kinematic and
semi-kinematic mounts
* Uses examples and case studies to illustrate the concepts and
equations presented in the book
* Provides supplemental materials on a companion website
Focusing on fundamental concepts and first-order estimates of
optomechanical system performance, Optomechanical Systems
Engineering is accessible to engineers, scientists, and
managers who want to quickly master the principles of
optomechanical engineering.
