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 offaxis 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.
