Abstract :
An acousto-optical imaging system for in-situ measurement of the high temperature distribution in micron-size specimens is described. It is based on image acquisition in narrow-band spectral intervals and reconstruction of the Planck law in each pixel. It contains the microscope objective lens, imaging acousto-optic tunable filter, optical coupler and CCD camera. The system is designed to measure temperature distribution inside minerals and functional materials phases subjected to high pressure and high temperatures in a diamond anvil cell heated by a high power laser which is required for studying phase transition and measurements acoustical properties of materials under high pressure in geophysics and materials sciences.
