Abstract:	Based on an optical reflection model in polished multilayered surfaces, reflectance and transmittance for the incident angle of the laser beam have been analyzed. The analysis demonstrates that the laser incident angle used in the previous experiment is optimum for measuring in-plane mode shapes in polished resonators with gold and chrome electrodes.
