New algorithm for extreme temperature measurements. (English) Zbl 0962.74042

Summary: We present a new algorithm for measurement of extreme temperature. This algorithm reduces the measurement of unknown temperature to solving of an optimal control problem, using a computer. Based on this method, a new device for extreme temperature measurements is projected. It consists of a hardware part that includes some standard temperature sensors, and it also has a software section. The principal component of the device is a rod. The variation in the temperature, which is produced near one end of the rod, is determined using some temperature measurements at the other end of the rod, and using the new algorithm described here. The mathematical model of the device and the algorithm are explained in detail. At the same time, some possible practical implementations and a collection of simulations are presented.
