28、wide 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 t
29、hat 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
30、 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
31、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 12005 was prepared by Tec
32、hnical 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. EN ISO 12005:2003 Licensed Copy: sheffieldun sheffieldun, na, Sun Nov 19 12:51:38
33、GMT+00:00 2006, Uncontrolled Copy, (c) BSI 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 lase
34、rs with a high divergence angle. 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
35、 in Annex A, together with a description of the Stokes parameters which are needed in that case.

36、 2006, Uncontrolled Copy, (c) BSI ANRETNIITOTS LANDNADRAISO 00213002:5)E( Lasers and laser-related equipment Test methods for laser beam parameters Polarization 1Scope This International Standard specifies a method for determining the polarization status and, whenever possible, the degree of polariz
37、ation 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 method for determining the direction of the plane of oscillation i
38、n 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 very important for some applications of lasers with a high d
39、ivergence 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 of polarization of highly divergent laser beams, as well as
40、for the measurement of beams with large apertures. 2Normative references The following referenced documents are indispensable for the application of this document.
