Full title and description
STB BS ISO 2303-2019 — Optics and photonics — Optical transfer function — Methods of measurement (ISO 2303:2019, adopted as national/sectoral reference)
Abstract
This standard specifies methods for the measurement of the optical transfer function (OTF) of optical imaging systems. It describes procedures, test objects and measurement techniques for determining modulation transfer function (MTF), phase transfer function (PTF) and related quantities, enabling objective characterization of system imaging performance under defined conditions.

Scope
This standard gives standardized methods for measuring the optical transfer function of linear, time-invariant optical imaging systems. It covers test arrangements, suitable test objects and measurement and evaluation procedures to obtain the amplitude (MTF) and phase (PTF) components of the optical transfer function. The procedures apply to lenses and optical systems operating in one or two dimensions and are intended for laboratory and production verification of imaging performance.
Key topics and requirements
- Definition of optical transfer function (OTF), modulation transfer function (MTF) and phase transfer function (PTF).
- Recommended test objects and targets for OTF measurement (e.g., bar/edge/slit and sinusoidal patterns).
- Measurement setups and alignment requirements for accurate OTF determination.
- Procedures for capturing and processing measurement data, including Fourier analysis and correction for system artifacts.
- Calibration, normalization and reporting formats for MTF/PTF results.
- Considerations for sampling, detector characteristics, and aliasing effects.
- Uncertainty evaluation and validation of measurement results.
Typical use and users
Used by optical engineers, lens manufacturers, camera and sensor developers, metrology laboratories and quality assurance personnel who need reliable, repeatable measures of imaging performance. Applied in R&D, production testing, acceptance testing and comparative evaluation of optical systems and imaging components.
