Abstract
We propose and demonstrate a new practical method for measuring the to tal/diffuse hemispherical reflectances and simultaneously reflected ra diance factor of diffuse reflective substrates. This method involves t he use of a collimated and focused monochromatic light beam and a spec ified integrating-sphere detector. The reflected radiance factor can b e computed from the differential of the reflectance as a function of t he polar angle.
