Optics and photonics. Optical transfer function. Application - Telescopes Ingestion-build-59651 Hence BS EN 4109 walks1 Scope 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.
