Abstract Measuring a bidirectional reflectance distribution function (BRDF) requires long time because a target object must be illuminated from all incident angles and the reflected light must be measured from all reflected angles. A high-speed method is presented to measure BRDFs using an ellipsoidal mirror and a projector. The method can change incident angles without a mechanical drive. Moreover, it is shown that the dynamic range of the measured BRDF can be significantly increased by multiplexed illumination based on the Hadamard matrix.
