Lasers and laser-related equipment. Test methods for determination of the shape of a laser beam wavefront - Terminology and fundamental aspects Ingestion-build-68772 The description is carried out1 Scope This part of ISO 15367 specifies methods for the measurement of the topography of the wavefront of a laser beam by measurement and interpretation of the spatial distribution of the phase of that wavefront across a plane approximately perpendicular to its direction of propagation. Requirements are given for the measurement and analysis of phase distribution data to provide quantitative wavefront parameters and their uncertainty in a test
