Metrology and test technologies for optical properties of materials:development status and trends
This paper summarizes the research progress of metrology and test technology for optical properties of ma-terials,including internationally mutual recognized calibration and measurement capabilities,international comparisons,national metrology primary standard facilities,verification regulations and calibration specifications,and national stan-dards.It introduces the methods,principles,capability,and uncertainties of primary standards such as spectral rule trans-mittance,spectral diffuse reflectance,and diffuse transmittance visual density measurement facilities,as well as social common standards such as wavelength in a continuous wide spectrum.It also summarizes the national standards on the test methods for the comprehensive optical,mechanical,thermal,and chemical properties of optical materials with color-less optical glass as an example.It concludes that the national metrology and test technology for optical properties of mate-rials have been improved rapidly,with significant international and domestic influence,effectively ensuring the research and application of high-quality optical materials and high-precision material optical property measurement instruments,and promoting the high-quality development of the national optical material industry.With increasing demands for ad-vanced optical materials in cutting-edge fields,it is very important to steadily enhance the technical infrastructure,con-tinuously expand the measurement range,and deeply focus on the physical essences,to underpin the key metrology and test technology for optical properties of materials to further play a key role in the fields of precision measurement,efficient perception,digital reconstruction,intelligent decision-making,human-computer interaction and so on.
