Title: DEVICE AND PROCESS FOR ANALYSING A CHANGE IN PHYSICAL STATE OF A MATTER THAT IS NOT PURELY GASEOUS
Abstract:
The invention relates to a process for analysing a change in physical state of a matter that is not purely gaseous, in which: - at least one part of the free surface of the matter is maintained under coherent electromagnetic radiation; - the temperature of the matter is varied over time; - a plurality of measurements of at least one magnitude of at least one part of the electromagnetic radiation radiated by the matter are carried out during the temperature variation, the various measurements of the plurality of measurements being carried out at different times and for given temperatures of the matter, and; - a value representative of a rate of variation -in particular of a rate of fluctuation- of each magnitude measured and of the change in physical state of the matter is deduced from the plurality of measurements. The invention also extends to a device (1) for analysing a change in physical state of a matter (3) that is not purely gaseous.
