Описание (английский):

ISO 9334:2012 defines terms relating to the optical transfer function and indicates, where pertinent, the mathematical relationships between those terms. It also defines important parameters that should be specified in connection with optical transfer function testing. The terms and parameters defined in ISO 9334:2012 apply to all measurements of the optical transfer function for optical, electro‑optical and other imaging systems.

Overview

ISO 9334:2012 - Optics and photonics: Optical transfer function - Definitions and mathematical relationships provides a standardized vocabulary and the fundamental mathematical relationships used when measuring and reporting the Optical Transfer Function (OTF) of imaging systems. The standard defines terms, key parameters to be specified for OTF testing (for example focus setting and spatial frequency range), and the basic requirements needed to ensure comparable, accurate OTF measurements across instruments and laboratories. It applies to optical, electro‑optical and other imaging systems.

Key topics and requirements

Definitions and terminology: Precise definitions of OTF-related terms to ensure consistent interpretation in measurement and reporting.

Mathematical relationships: Core relationships that link OTF to other image‑describing quantities (e.g., the reduction of modulation and phase shift of sinusoidal spatial components).

Measurement parameters to specify: Parameters that must be reported to guarantee equivalence of results (notably focus setting, spatial frequency range and other test conditions).

Linearity and isoplanatism: Discussion of the conditions under which the OTF model is valid - the standard recognizes limits where a system is linear and isoplanatic and how to treat measurements when these conditions only hold over restricted ranges.

Multiplicative (product) property: The OTF of incoherently coupled components can be treated multiplicatively (overall OTF = product of component OTFs) - with caveats for coherent coupling where whole‑system testing is required.

Instrumentation and accuracy: Basic specifications for measurement instrumentation and procedures needed to achieve defined measurement accuracy and comparability.

Practical applications

Standardizing OTF measurements for:

Lens and camera manufacturers verifying image‑forming performance
Optical designers predicting system behavior from component data
Test and calibration laboratories ensuring inter‑lab equivalence
Quality assurance and acceptance testing for electro‑optical systems
R&D teams comparing imaging components or integrated systems

Useful in product specification, procurement, verification, and scientific reporting where objective, repeatable image quality metrics (OTF/MTF and phase response) are required.
