Provides general guidance on evaluation of the error sources in optical transfer function (OTF) equipment and in the use of this information for estimating mistakes in a measurement of OTF. In addition it supplies guidance on assessment and specification of a general accuracy value for a defined measuring equipment, in addition to recommendation of routine assessment methods.

This International Standard gives general guidance on evaluating the sources of error in optical transfer function (OTF) equipment and in using this information to estimate errors in a measurement of OTF. It also gives guidance on assessing and specifying a general accuracy value for a specific measuring equipment, as well as recommending methods of routine assessment.

The main body of this International Standard deals exclusively with the modulation transfer function (MTF) part of the OTF. The phase transfer function (PTF) is dealt with relatively briefly in annexA.
