This edition of Optical Metrology contains a new chapter about computerized optical
processes, including digital holography and digital speckle photography. Chapter 2, on
Gaussian optics, and Chapter 5, on light sources and detectors, are greatly expanded
to include descriptions of standard imaging systems, light-emitting diodes and solid-state
detectors. Separate new sections on optical coherence tomography, speckle correlation, the
Fast Fourier Transform, temporal phase unwrapping and fibre Bragg sensors are included.
Finally, a new appendix about Fourier series is given.
