7、ion) is a worldwide federation of national standards bodies (IS0 member bodies). The work of preparing International Standards is normally carried out through IS0 technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be r
8、epresented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. IS0 collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Draft International Sta
9、ndards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 YO of the member bodies casting a vote.

13、l systems is to form an image that is geometrically similar to the object, except some particular systems such as fish-eye lenses and eyepieces, where this condition is deliberately not maintained. This function is accomplished ideally accord- ing to the geometry of perspective projection. Departure
14、s from the ideal image geometry are called distortion. The distortion is a position- dependent quantity which generally has a vectorial character. In a given image plane (which may also lie at infinity), this vector, representing the difference between theoretical and real image position, has a radi
15、al and a tangential component. In optical systems, the tangential component is basically conditioned by imperfect rotational symmetry. The systems manufactured in accordance with the present state of the art have a neg- ligible tangential distortion. A tangential component of the distortion ap- pear
16、s, however, as primary aberration in the case of electromagnetically focused electrooptical systems. This International Standard deals only with the radial distortion. For special systems, e.g. certain electrooptical sys- tems, an expansion may become necessary to include vectorial represen- tation.

18、IONAL STANDARD 0 IS0 IS0 9039:1994(E) Optics and optical instruments - Quality evaluation of optical systems - Determination of distortion 1 Scope This International Standard specifies methods of de- termining distortion in optical systems for the pur- poses of quality evaluation. It applies to opti
19、cal imaging systems in the optical spectral range from IO0 nm to 15 O00 nm which, by their design, aim at a rotationally symmetric image geometry. It is applicable to electrooptical imaging systems provided that adequate rotational symmetry of the image is guaranteed. It does not apply, there- fore,
20、 to anamorphic and fibre optic systems. 2 Normative reference The following standard contains provisions which, through reference in this text, constitute provisions of this International Standard. At the time of publi- cation, the edition indicated was valid. All standards are subject to revision,
21、and parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most re- cent edition of the standard indicated below. Mem- bers of IEC and IS0 maintain registers of currently valid International Standards. IS0 9334:-”, Optics and optical
22、instruments - Op- tical transfer function - Definitions and mathematical relationships. 3 Definitions For the purposes of this International Standard, the following definitions apply. 3.1 distortion: Measure of the deviation of the extra-axial image points from the ideal image points in a given plan
23、e lying parallel to the reference plane of the system. If the image plane is at infinity, the image positions are given in terms of tangents of field angles. 3.2 reference plane: Plane corresponding to a physical feature of the device under test which is used for alignment e.g. a mounting flange or
24、a fixture specially mounted for that purpose. 3.3 absolute distortion, Va: Distance in the radial direction between the observed image point and the ideal image point, expressed in millimetres or micro- metres. 3.4 relative distortion, I I , : Distance in the radial di- rection between the observed
