Geometric, Physical, and Visual Optics

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.

* Emphasizes conceptual understanding and development of optical intuition * Uses the vergence-dioptric power-wavefront approach * Helpful review for optometry boards and qualifying examinations
