Textbook in PDF format.

The expanded 4th edition of this classic optics text is aimed at those wishing to apply their knowledge of optics to engineering problems, and provides a sound introduction to the basic principles of optics for engineering students. It describes fundamental material including Fourier optics, diffraction theory, geometrical optics, and lenses, and goes on to cover important topics such as optical signal processing, holography, tomography, optical communication, electro- and acousto-optic devices, integrated optics, 3D imaging and optical distance measurement.
Comprehensively updated throughout, this new edition features a major additional section on optical measurement techniques, including chapters on scanning methods, structured light pattern projection methods, depth measurement using a microscope, coherent as well as incoherent interferometry and distance mapping using CCD cameras.
Fully illustrated, the text includes numerous practical examples, together with worked exercises and end-of-chapter problem sets
