Textbook in PDF format

This book is intended to complement and enhance current works which provide essential know-how for practising optical designers and students of applied optics. Classical imaging systems are generally designed using the laws of geometrical optics to trace rays through a series of lenses and mirrors. Diffraction is considered in terms of a physical process which ultimately limits the attainable theoretical performance, but not as the fundamental mechanism by which light is deviated and focused. However, the process of diffraction may also be used advantageously as the fundamental mechanism by which light is manipulated; thus, a diffractive optical element (DOE) may, in the most general sense, be defined as an optical element which operates in this way.
