About
Clarence J. Zarobila is a leading figure in precision optical metrology, whose work at the National Institute of Standards and Technology (NIST) has fundamentally advanced the measurement of light scattering from surfaces. His primary research focuses on bidirectional reflectance distribution function (BRDF) measurements, the development of state-of-the-art gonioreflectometers, and the creation of diffuse reflectance standards critical for remote sensing calibration. Zarobila’s most significant contribution is the design and realization of the NIST Robotic Optical Scatter Instrument (ROSI), a revolutionary robotic-arm-based goniometer that enables both in-plane and out-of-plane BRDF measurements across ultraviolet to short-wave infrared wavelengths. As the national reference instrument for such measurements, ROSI has set the global standard for accuracy, with its foundational 2013 paper garnering 18 citations. He further advanced the field by pioneering a tunable supercontinuum fiber laser source for the STARR II gonioreflectometer, expanding spectral measurement capabilities. His work directly supports the calibration of satellite sensors and climate monitoring instruments, ensuring the reliability of Earth observation data. With a career dedicated to pushing the boundaries of optical scatter metrology, Zarobila’s instruments and standards remain indispensable tools for researchers and engineers worldwide.
