Paper Abstract

A method of evaluating the uniformity of an illumination pattern of an automotive head lamp on a road surface is presented. The most critical area where the beam pattern uniformity can be identified is the high intensity region. In this area two evaluating parameters, correlation set, and contrast level are discussed. In a low intensity region of the illumination pattern, the same principle can be applied.
