Abstract
The dynamic bias in on-line thickness measurement employing the radiation transmission technique is formulated in terms of the speed of the material and the measurement time interval. For a number of materials with irregular surfaces, the bias increases with the speed of the material as well as with the measurement time interval. However, for some other irregular surfaces and under special measurement conditions, the bias is independent of both the speed and the measurement time interval but dependent on other physical properties. A combination of suitable radiation, low speed and extremely short time interval of transmission measurement will reduce the bias and consequently improve the result in most cases.
