Standards Development
This document specifies the design and metrological characteristics of digital holographic microscopy (DHM) instruments for the areal measurement of surface topography. Because surface profiles can be extracted from areal surface topography data, the methods described in this document are also applicable to profiling measurements.
Non-contact digital holographic microscopy (DHM) instruments are widely used in precision manufacturing, materials science, and micro-nano device inspection. As a non-invasive, 3D optical imaging technology, DHM realizes real-time microscopic morphology reconstruction, quantitative topographic analysis and metrological characterization without physical contact, mechanical scanning or sample staining, holding unique advantages over traditional microscopic and contact measurement tools. Core DHM technologies are mature and widely verified in industrial and academic practice, with strong global demand for unified international specifications.
Despite fast technological progress and growing global application, there is no international standard for DHM instruments. Worldwide, manufacturers, labs and research institutes apply inconsistent specifications, evaluation methods and terminology, leading to incomparable test data, poor interoperability, high compliance costs and international trade & technical cooperation barriers. This also disrupts fair market competition, reduces measurement reliability in critical applications, and limits the global industrial development of the DHM instruments. This new work item aims to develop an international standard that defines terms, instrument requirements, design features, and metrological characteristics for non-contact DHM instruments. It will establish unified global terminology, design frameworks, performance benchmarks and quality assurance rules for general industrial, scientific and biomedical DHM systems.
This standard will deliver clear global benefits: it unifies technical baselines for DHM development and manufacturing, improves product consistency and measurement comparability, removes international technical trade barriers, cuts enterprise R&D and compliance costs, provides unified evaluation criteria for users and regulators, and supports reliable non-contact microscopic testing across high-demand fields.
