Optics and photonics. Optical transfer function. Principles and procedures of measurement1 Scope This International Standard gives general guidance for the construction and use of equipment for measurement of the optical transfer function (OTF) of imaging systems. This International Standard specifies important factors that can influence the measurement of the OTF, and gives general rules for equipment performance requirements and environmental controls. It specifies important precautions that should be taken to ensure accurate
