22、I SO 4002 All irthgs erse/devrTsuo iordts rsesvr vForeword 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
23、 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 Internationa
24、l 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
25、 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
26、 patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 15902 was prepared by Technical Committee ISO/TC 172, Optics and photonics, Subcommittee SC 9, Electro-optical systems.

32、rse/devrTsuo iordts rsesvr viiIntroduction The term diffractive optical element is used for those optical elements which convert an input wavefront to a predetermined output wavefront (or wavefronts) in free space by means of the phenomenon of diffraction. There has been a rapid increase in the use
33、of diffractive optical elements, especially in the field of optical data storage, and they are essential components in optical and electro-optical systems. They are used in a wide variety of applications. EN ISO 15902:2005IS:20951 O4002(E/F) viii I SO 4002 All irthgs erse/devrTsuo iordts rsesvrIntro

37、sfor diffractive optical elements for free spacepropagation. The purpose of these definitions is toprovide an agreed-upon common terminology that will reduce ambiguity and misunderstanding andthereby aid in the development of the field ofdiffractive optics. La prsente Norme internationale dfinit les
38、 termes de base de loptique diffractive et des lments doptique diffractive en espace libre. Lobjet de ces dfinitions est de fournir une terminologie commune reconnue qui limitera les ambiguts et les incomprhensions et de ce fait apportera une aide au dveloppement du domaine de loptique diffractive.
