Abstract

Three methods are described for measurement of glare from automotive chromium surfaces. The first is a performance measure: a glare illumination technique that measures at the driver's eye location the amount of light reflected to that location. The other two methods measure a surface property rather than performance. One is the standard glossmeter method of measuring gloss on flat surfaces. The other is a substitute gloss image method that measures gloss on both flat and curved surfaces. Results when using the glare illumination technique on flat and curved surfaces, with both bright and satin chromium finishes, indicated that glare decreased as surface curvature was increased. The effect of the satin finish was a reduction in glare from flat surfaces but not from curved surfaces.
