Abstract
Luminance responsivity is a photometric quantity that realizes the brightness of a surface. Recently, a luminance responsivity scale has been presented [2, 3], which is based on a separate measurement of the spectral responsivity, as well as the distance and size of the aperture. The luminance responsivity value at the aperture plane of an integrating sphere is obtained from the measurements. In this work, we present our analysis of the unit of luminance responsivity.
