High temperature and luminous plasma make it difficult to study the surface of nanopowders during combustion, particularly, the combustion of aluminum-based nanopowders. The noncontact observation method-laser speckle correlation (LSC) in this work is used for remote characterization of changes in the surface of aluminum nanopowder during combustion in air. The observation results using LSC at a varying distance of up to 5 m were verified by simultaneous high-speed video recording of speckle patterns, analyzing the correlation coefficient of speckle patterns, and comparing the data obtained with direct observation of the combustion process. The results demonstrated the efficiency of using the LSC method for remote characterization of changes in the surface of an object shielded by a luminous layer. The simple hardware implementation makes the LSC method potentially more valuable in the study of various high-temperature processes.
