Optics and photonics. Optical transfer function. Principles of measurement of modulation transfer function (MTF) of sampled imaging systems1 Scope This International Standard specifies the principal MTFs associated with a sampled imaging system, together with related terms, and outlines a number of suitable techniques for measuring these MTFs. It also defines a measure for the aliasing related to imaging with such systems. This International Standard is particularly relevant to electronic imaging devices such as digital still and video cameras and the detector arrays they embody.

BS 8214 is applicable only to doors that are designed to provide fire resistance ratings of up to and including 2 h when tested in accordance with BS 476-22 or BS EN 1634-1
