Andere physische Formen: Also available in print version.Zusammenfassung: This is a practical book on wavefront sensing. Emphasis is on principles and techniques, rather than detailed mathematical analysis of such systems. The goal is to provide the reader with a qualitative understanding of wavefront sensor operationZusammenfassung: 6. Indirect wavefront measurement, Part II. 6.1. Introduction; 6.2.
