摘要

The UNL Glare Apparatus was designed to systematicallynvary the four primary factors which affect discomfort glare, includingnsource luminance, source size, source position, and backgroundnluminance. It was also designed to have considerable flexibility tonresearch many additional independent and dependent variables. Thentheatrical lighting fixtures used in the apparatus caused a significantnproblem for scientific research: the output from the fixture did notnproduce a uniform illuminance on the target. A “uniformity” filter wasncreated to produce uniform illuminance on the stimulus. This paperndescribes the nonuniform illuminance problem and the creation of an“uniformity” filter to correct the problem. The complete Matlab codenused to generate the filter is available from the authors.
