| Abstract: | An optical method of measuring the pressure distribution in an automobile tyre contact area is reported. The method relies on the phenomenon of frustrated total internal reflection to produce a video image in which the brightness is a measurement of the pressure at any point. Conversion of this monochrome picture via a colour synthesizer allows the contact area to be displayed as a colour contour map of pressure. |
