Abstract :
The resonant prism-coupling technique for measuring of light beam intensity distribution is presented. This approach is based on recording of the angular dependence of intensity of the reflected laser beam in the case of excitation of guided mode in testing thin-film structure. Analysis of the spatial intensity spectrum is considered.
