Recent Advances in Resistance Thermometry Readouts

Recent innovations and technological advances have significantly enhanced the performance and utility of digital resistance thermometry readouts. The readout is an important component of a temperature calibration system, especially when used with a standard platinum resistance thermometer, since the readout contributes to the accuracy, reliability, and efficiency of the system. Accurate digital...

Linking the thermodynamic temperature to an optical frequency: recent advances in Doppler broadening thermometry

Laser spectroscopy in the linear regime of radiation-matter interaction is a powerful tool for measuring thermodynamic quantities in a gas at thermodynamic equilibrium. In particular, the Doppler effect can be considered a gift of nature, linking the thermal energy to an optical frequency, namely the line centre frequency of an atomic or molecular spectral line. This is the basis of a relativel...

Volumetric thermometry

Background/introduction Many applications of thermal therapy would benefit from temperature distribution measurements with high spatial and temporal resolution that cover a large 3D volume. Although MRI can acquire 3D temperature measurements, it is not possible to obtain fully sampled 3D MRI measurements that cover the insonified field of view with sufficient spatial and temporal resolution fo...

Nuclear Thermometry

The concept of a nuclear temperature was introduced some seventy years ago in pioneering works performed by Bethe [1] and Weisskopf [2]. The goal was to describe the formation and the decay of a compound nucleus in reactions induced by light projectiles, mostly neutrons. Later on, the concept of a nuclear temperature was extended to reactions involving highenergy projectiles and heavy ions [3]....
