Geometric, Physical, and Visual Optics


  • Michael Keating, PhD, Professor, Michigan College of Optometry, Ferris State University, Big Rapids, MI

Completely revised and updated, you will benefit from new and rewritten sections on: axial magnification • Jackson Cross Cylinder tests • retinoscopy reflex motions • field of view • the optics of indirect ophthalmoscopy • optical aberrations • diffractive lenses • the Doppler shift • lasers and the similarities and differences of Gaussian laser beams versus the propagation of light from a point source • plus, a new appendix on angles and basic trigonometry.

Although not a matrix optics text, matrices are used extensively in the chapters on spherical systems and off-axis aspects of astigmatism. In particular, the matrix treatment of astigmatism serves as a foundation for the recently developed, much improved statistical techniques that deal with refractive corrections and astigmatism in all its aspects.
