Lasers and laser-related equipment - Test methods for determination of the shape of a laser beam wavefront - Part 1: Terminology and fundamental aspects (ISO 15367-1:2003)
ISO 15367-1:2003 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 report.
The methods described in ISO 15367-1:2003 are applicable to the testing and characterization of a wide range of beam types from both continuous wave and pulsed lasers. Definitions of parameters describing wavefront deformations are given together with methods for the determination of those parameters from phase distribution measurements.
Laser und Laseranlagen - Prüfverfahren für die Bestimmung der Wellenfrontform von Laserstrahlen - Teil 1: Begriffe und grundlegende Aspekte (ISO 15367-1:2003)
Die vorliegende Internationale Norm legt Messverfahren für die Topografie der Wellenfront eines Laserstrahls durch Messung und Auswertung der räumlichen Verteilung der Phasen dieser Wellenfront in einer Ebene rechtwinklig zu ihrer Ausbreitungsrichtung fest. Es werden Anforderungen für die Messung und Analyse von Phasenverteilungen aufgestellt, die die quantitative Angabe von Wellenfrontparametern und deren Messunsicherheit in einem Prüfbericht ermöglichen.
Die in dieser Internationalen Norm beschriebenen Verfahren gelten für die Prüfung und Beschreibung vieler Strahlenarten von Dauerstrichlasern sowie Pulslasern. Es werden Parameterdefinitionen für die Verformung von Wellenfronten sowie Verfahren zur Ermittlung dieser Parameter aus Messungen der Phasenverteilung angegeben.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 15367-1 was prepared by Technical Committee ISO/TC 172, Optics and optical instruments,
Subcommittee SC 9, Electro-optical systems.
ISO 15367 consists of the following parts, under the general title Lasers and laser-related equipment — Test
methods for determination of the shape of a laser beam wavefront:

ISO 15367-1:2003(E)
Introduction
It is important, when designing, operating or maintaining a laser system, to be able to ensure repeatability,
predict the propagation behaviour of the laser beam and to assess the safety hazards. There are four sets of
parameters that could be measured for the characterization of a laser beam:
power (energy) density distribution (ISO 13694);
beam width, divergence angle and beam propagation factor (ISO 11146);
phase distribution (ISO 15367);
spatial beam coherence.
This part of ISO 15367 defines the terminology and symbols to be used when making reference to or
measuring the phase distribution in a transverse plane of a laser beam. It specifies the procedures required
for the measurement of
the azimuth of the principal planes of the phase distribution;
the magnitude of astigmatic aberrations;
evaluation of the wavefront aberration function and the RMS wavefront deformation.
A useful technique for qualitative assessment of a beam is visual inspection of the fringe pattern in
interferograms or an isometric view of a wavefront surface. However, more quantitative methods are needed
for quality assurance and transfer of process technology. The measurement techniques indicated in this part
of ISO 15367 allow numerical analysis of the phase distribution in a propagating beam and can provide
recordable quantitative results.
While it is quite possible to ascribe other conventional aberrations (e.g. coma or spherical aberration) as well
as astigmatism to a laser beam, these are not commonly used. Departure of the wavef
