| Abstract: | Owing to their merits of non-interference with the original physical field, high accuracy and convenient recording, optic methods are widely used in thermophysical property measurement and materials science. Investigations of the author including density field measurement based on Lorenz-Lorentz principle, surface teusion measurement of binary two-phase mixture based on density and the height of liquid column; liquid thermal diffusivity measurement by laser pulse, and the simultaneous measurement of temperature and density field by two- laser interferometry are described. Material defects detected by holographic interferometry are also briefly discussed. Optic systems and the main procedures are given and points for attention in experimental resuls analysis are suggested. |
