18‐1: Combining Annulus and Variable Aperture Source Methods to Separate Specular, Haze and Lambertian Reflection Components of ePaper Displays.

The annulus light source method separates specular and diffuse components of reflected glare from display surfaces. Combining it with the variable aperture source method delivers source‐size dependence. Measuring diagnostic reflection samples and ePaper with mirror‐like or scattering surfaces confirmed that the source‐size dependence of reflected glare comes from haze scatter. [ABSTRACT FROM AUTHOR]
