Abstract

Several different approaches have been used in the development of techniques for analysis of either polarization or space charge distributions. An especially promising one is to use a nonuniformly distributed driving force to elicit an electrical response from the electret. For example, a nonuniformly distributed mechanical force, such as a pressure, will interact with the spatially distributed polarization or space charge to produce a piezoelectric response. The use of a nonuniformly distributed temperature (thermal force) was developed extensively by Collins and implemented by Mopsik and De Reggi. We have developed a new method based on the use of a nonuniformly distributed thermal force, the Laser Intensity Modulation Method (LIMM). This technique has advantages in ease of use, flexibility, scope and quality of results.
