Radiation Thermometry—Sources of Uncertainty During Contactless Temperature Measurement

Short Time Annealing on a microsecond to nanosecond scale presents new challenges to temperature measurement. Pyrometers are widely used owing to their commercial availability, short response time, easy handling and contactless operation. However, they hold a source for considerable measurement errors. False readings are easily gained producing large errors during temperature measurement.
This chapter intends to give the reader an overview on characteristic features associated with Radiation Thermometry in a broader sense and more specifically with Pyrometry.
