| Abstract: | Laser photothermal deflection method for nondestructive contactless testing inhomogencity and defects in surface or subsurface of sob'd materials is described. The testing set up is designed and established. Some tested results including the measurements of absorbance of optical thin films, and grey image detection of surface damage of optical thin films by powerful laser., flaws in C/C composed material ana analogous defects in subsurface of metal A1 are shown. |
