OPTICAL DESIGN

Photonics Spectra
Jan 2008
SPIE-Press_Fischer.jpgBased on a SPIE professional course, the book Optical System Design, Second Edition, presents techniques and diagrams that illustrate major design procedures. The 624-page resource features new chapters on polarization, diffractive optics, optomechanical design, systems analysis and stray light suppression. It includes chapters on glass selection, geometrical aberrations and how to eliminate them, spherical and aspheric surfaces, computer performance evaluation and optical path difference. Numerous examples are provided to explain the techniques. Applications such as digital imaging, machine vision and telecommunications are addressed. Robert E. Fischer, Biljana Tadic-Galeb and Paul R. Yoder Jr.; SPIE Press, Bellingham, Wash.; McGraw-Hill Companies, New York, 2008; $85, SPIE members; $100, nonmembers.


GLOSSARY
diffractive optics
Optical elements that use diffraction to control wavefronts. Diffractive optical elements include diffraction gratings, surface-relief diffractive lenses, holographic optical elements and computer-generated holograms. Fabrication methods include diamond machining, interference of coherent beams (holography), injection molding and advanced microlithographic techniques. See also binary optics; holographic optical element.
polarization
With respect to light radiation, the restriction of the vibrations of the magnetic or electric field vector to a single plane. In a beam of electromagnetic radiation, the polarization direction is the direction of the electric field vector (with no distinction between positive and negative as the field oscillates back and forth). The polarization vector is always in the plane at right angles to the beam direction. Near some given stationary point in space the polarization direction in the beam...
