Реферат: | eng: We demonstrate that combining the laser heating (LH) system in a diamond anvil cell (DAC) with a tandem acousto-optical tunable filter (TAOTF) allows measurement of the temperature distribution (TD) under infrared (IR, 1064 nm) LH of a specimen under high pressure in a DAC. The main component of the system is a TAOTF synchronized with a video camera. The system allows TD mapping within a temperature range of approximately 1000-2000 K on the surface of a laser-heated object (Fe plates) at high pressure in a DAC with a spatial resolution 2 mu m by fitting the actual signal to Planck's equation at each point.
