24、03 iv 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 whi
25、ch 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 m
26、atters 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 cir
27、culated 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 respon
28、sible for identifying any or all such patent rights. ISO 12005 was prepared by Technical Committee ISO/TC 172, Optics and optical instruments, Subcommittee SC 9, Electro-optical systems. This second edition cancels and replaces the first edition (ISO 12005:1999), which has been technically revised.
29、ENISO12005:2003 v Introduction This International Standard specifies a relatively quick and simple method, requiring minimum equipment, for determining the state of polarization of a laser beam. This method is for well-polarized laser beams, including those emitted by lasers with a high divergence a
30、ngle. However, if more completeness in the determination of the polarization status is required, the use of a more sophisticated analysing device is necessary. Although not within the scope of this International Standard, the principle of operation of such devices is given in Annex A, together with
31、a description of the Stokes parameters which are needed in that case. ENISO12005:2003 . ivANRETNIITOTS LANDNADRA ISO 00213002:5)E( Lasers and laser-related equipment Test methods for laser beam parameters Polarization 1S c o p e This International Standard specifies a method for determining the pola
32、rization status and, whenever possible, the degree of polarization of the beam from a continuous wave (cw) laser. It can also be applied to repetitively pulsed lasers, if their electric field vector orientation does not change from pulse to pulse. This International Standard also specifies the metho
33、d for determining the direction of the plane of oscillation in the case of linearly polarized (totally or partially) laser beams. It is assumed that the laser radiation is quasi- monochromatic and sufficiently stable for the purpose of the measurement. The knowledge of the polarization status can be
34、 very important for some applications of lasers with a high divergence angle, for instance when the beam of such a laser shall be coupled with polarization dependent devices (e.g. polarization maintaining fibres). This International Standard also specifies a method for the determination of the state
35、 of polarization of highly divergent laser beams, as well as for the measurement of beams with large apertures. 2 Normative references The following referenced documents are indispensable for the application of this document.

38、rtain directions NOTE This is a fundamental phenomenon which can be explained by the concept that electromagnetic radiation is a transverse wave motion, i. e. the vibrations are at right angles to the direction of propagation. It is customary to consider these vibrations as being those of the electric field vector. 3.2 state of polarization classification of polarization as linear, random, circular, elliptical or unpolarized ENISO12005:20031
