This document specifies a method of testing telescopes in terms of imaging states aimed at making valid optical transfer function (OTF) measurements.
This document includes two annexes (Annex A and B) that provide information on the more recent techniques for measuring optical transfer function and methods of deriving image quality criteria from such measurements.nd edition 2020-01 Optics and photonics — Optical transfer function — Application — Part 3: Telescopes Optique et instruments d'optique — Fonction de transfert optique — Application — Partie 3: Télescopes Reference number ISO 9336-3:2020(E) ？ ISO 2020 ISO 9336-3:2020(E) COPYRIGHT PROTECTED DOCUMENT ？ ISO 2020 All rights reserved.
