Clarence Zarobila (Assoc)

Mr. Zarobila is a physicist in PML's Sensor Science Division. He co-developed the Robotic Optical Scattering Instrument (ROSI), the national reference instrument for specular and bi-directional reflectance measurements. For that work he and his colleagues received the NIST Judson C. French award. He also co-developed the air-LUSI telescope, the "eye" of a system which measures the spectral irradiance of the moon from an aircraft flying near the top of the atmosphere. He supports NIST STARS and a variety of other projects in PML and EL by developing optical and engineering models. His research interests include interferometry, spectrophotometry, color and appearance, and sensing using optical and fiber-optic techniques.
