Paper Abstract

A draft proposal for a documentary standard on the Optical Transfer Function has been prepared by a task force reporting to American National Standards Committee PH3 (Photographic Apparatus), subcommittee PH3-2 (Lenses, Projection and Printing Equipment). This proposal is currently under review by PH3, and its present form and status are described briefly here. The aims of the proposed document are to provide, for imaging devices in general and particularly for lenses, a consistent set of definitions and nomenclature for the spread, transfer, and pupil functions, the relations among them, and the parameters on which they may depend; to describe basic principles of measurement, using several alternative measuring techniques as detailed examples, and advise on some common sources of error and their minimization: to enumerate conditions that need to be specified in connection with OTF testing; and to provide a basic format and nomenclature for specifying the extent of such tests and for reporting the results. It is expected that subsequent standards, using this document as foundation, can concisely specify particular test limits or measuring methods, as appropriate to particular devices or applications. Some other documentary standards relating to image quality, under current consideration by PH3-2, are also very briefly described.
