Overview
IEC 63145-22-10:2020 - Eyewear display, Part 22-10: Specific measurement methods for AR type – Optical properties defines standard measurement conditions and test methods for determining the see-through optical properties and imaging quality of augmented reality (AR) eyewear displays. It covers transmission characteristics and ambient optical performance for AR eyewear (excluding contact‑lens type displays). The standard sets environmental and setup requirements, measurement system definitions, test patterns and reporting conventions to ensure repeatable, comparable optical characterization.
Key Topics
- Scope and exclusions
- Applies to AR eyewear displays (see‑through optics); contact lens displays are out of scope.
- Standard measurement conditions
- Environmental: temperature 22 °C to 28 °C, relative humidity 25 % to 85 %, pressure 86–106 kPa.
- Requirements for power supply, warm‑up time and dark room conditions.
- Measurement systems
- Defined coordinate systems (spherical and Cartesian) for angular tests and Field of View (FOV) referencing.
- Use of a Light Measuring Device (LMD) and recommended stage/setup arrangements.
- Test patterns (e.g., checkerboard) and specified measuring points (center and multi‑point grids).
- Primary measurement methods
- Spectral directional transmittance - angular and spectral transmission of see‑through optics.
- Colour difference (∆u′v′) - chromaticity shifts introduced by the eyewear.
- Front side stray light (haze) - unwanted light reaching the eye that is not image- or scenery-forming (reported as H %).
- Contrast modulation - how the device modulates contrast across the image; includes test patterns and calculation/reporting methods.
- Reporting and symbols
- Standardized symbols and units (e.g., luminance L, transmittance T, chromaticity coordinates) and required report elements are specified.
Applications
- Performance validation of AR optical modules (waveguides, combiners, couplers).
- Acceptance testing in production and QA for AR eyewear manufacturers.
- Certification and compliance testing by independent test laboratories.
- R&D and comparative evaluation of see‑through display designs and materials.
- Integration guidance for system engineers assessing optical trade‑offs (transmission vs. stray light vs. colour fidelity).
Who should use this standard
- AR headset and smart‑glasses manufacturers
- Optical and display test laboratories
- Component suppliers (waveguide and combiner vendors)
- Certification bodies and compliance engineers
- Researchers in display optics and human factor evaluation
