The Laser Intensity Modulation Method (LIMM) is based on the measurement of the pyroelectric current generated by the material when it is heated with a laser beam which is intensity-modulated over a range of frequencies. A modification of this technique was developed which permits detailed profiling of the polarization distributions in a layer adjacent to the surface. Because of the analogy to LIMM, the new technique was named the Surface Laser Intensity Modulation Method (SLIMM). In this technique, the laser modulation frequencies are much higher than in LIMM and both the real and the imaginary components of the pyroelectric current are measured. A number of different materials were examined and some interesting features are observed.
