| Abstract: | A novel sensitive and simple scheme, referred to as the surface thermal lensing technique, has been introduced for detecting and analyzing the thermal waves to get information about weak absorptance of optical coatings. Its diffraction theory is presented briefly. Several samples for the Robin absorptance measurements have been tested using this method, and the measurement results have been analyzed. |
