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

mooring and towing small craft

It is intended to be used in conjunction with BS 10175 Investigation of potentially contaminated sites - Code of Practice

sulphated residue on ignition

Lubricants

Electrodeposition

— thermotropic liquid crystal polymers

The methods are applicable to:

accuracy and the resolution

— stirrer

to reduce inspection costs (by means ofreduced sampling inspection criteria) should consistently good quality be demonstrated over time

although many of its recommendations could be useful for that purpose
