Abstract
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.
