About
Thomas A. Germer is a leading figure in optical metrology, whose work has established the foundation for modern reflectance standards. His primary research focuses on the measurement of the Bidirectional Reflectance Distribution Function (BRDF), a fundamental property describing how light scatters from surfaces. Germer’s major contribution is the development of the NIST Robotic Optical Scattering Instrument (ROSI), a robotic-arm-based goniometer that enables highly accurate in-plane and out-of-plane BRDF measurements across ultraviolet to short-wave infrared wavelengths. His 2013 paper detailing ROSI and its application to diffuse reflectance standards for remote sensing has garnered 18 citations, while a comprehensive 2021 update on ROSI’s capabilities has received 11 citations. Beyond ROSI, Germer has advanced the field through the design of the STARR II facility, which employs a tunable supercontinuum fiber laser source to expand spectral measurement capabilities. His work directly supports remote sensing, climate science, and industrial quality control by providing the national reference for specular and diffuse reflectance. Germer’s instruments and methodologies are essential for calibrating satellite sensors and ensuring the accuracy of optical measurements worldwide.
