The results of theoretical and experimental studies of thermal and acoustic gratings excited at two media interface have been presented in the work. One medium is highly absorbing substance whereas another is transparent one at the spectral range of excitation and probing beams used. All the investigations have been conducted under reflecting configuration of probe beam. Aim of the work is to elaborate and experimentally implement the methods for thermal characterization and temperature remote sensing of metal and narrow band gap semiconductor surfaces, thin films as well as adjacent...
