Phototheriloplastic devices represent a candidate for optical holographic storage and real-time optical information processing. The typical band pass shaped frequency response of the devices already shows up in the so-called frost effect. For the design of thermo plastic devices it is important to determine the parameters limiting the transfer function. Measurements of the spatial frequency distribution of frost are compared with a first order theory of the deformation process. The agreement between theory and experiment is found to be satisfactory in view of the approximations made in the analysis.
