The second edition of Basics of Interferometry offers new chapters on white-light microscopy for medical imaging and on interference with single photonics (quantum optics). New sections detail developments such as gravitational wave detectors, optical signal processing and laser frequency measurements. The first part of the 247-page book covers basic topics such as interference in thin films and thick plates, and common types of interferometers. The second part covers techniques and applications of interferometry. P. Hariharan; Academic Press, an imprint of Elsevier, Burlington, Mass., 2007; $79.95.
