Joy Dunkers, Richard~undefined~undefined~undefined~undefined~undefined Parnas, C G. Zimba, R C. Peterson, Kathleen M. Flynn, J G. Fujimoto, B E. Bouma
Optical coherence tomography (OCT) is a non-destructive and non-contact technique to image microstructure within scattering media. The application of OCT to highly scattering materials such as polymer composites is especially challenging. In this work, OCT

Reflection Measurement Problems Arising from Haze

August 1, 1998
Author(s)
George R. Jones Jr., Edward F. Kelley
Irreproducibility in some reflection measurement methods arises from the observance of the haze component of reflection (non-regular-specular, non-Lambertian). Because of the haze component, the measured reflection is sensitive to the apparatus

Assessment of Color Measurement Systems Using Interference Filters

July 1, 1998
Author(s)
Paul A. Boynton, Eric Kelley
Spectroradiometers and tristimulus colorimeters are used in display measurements to measure color in one of several color space coordinate systems. How well these instruments can measure the color coordinates can be simply checked by using interference
