The music conservatory at Strasbourg conducts regular master classes. Yann Martin at University of Strasbourg conducts Master Class Management sessions. And advanced geometry is explored at Institute de Research en Mathematiques, Interactions, et Applications: Master class archives.
Introduction to Thermal Imagers. A thermal imager is a non-contact temperature measurement device. Thermal Imagers detect the infrared energy emitted, transmitted or reflected by all materials -- at temperatures above absolute zero, (0Â°Kelvin)-- and converts the energy factor into a temperature reading or thermogram.
Here's how thermal imaging works: 1  A special lens focuses the infrared light emitted by all of the objects in view. 2  The focused light is scanned by a phased array of infrared-detector elements. 3  The detector elements create a very detailed temperature pattern called a thermogram.
