Abstract:

An apparatus and method for measuring optical coupling coefficients is disclosed using the thermal expansion of a sample to reduce an externally applied tensile load of predetermined magnitude. The sample is illuminated with a known amount of incident energy. The absorption of this energy expands the sample which reduces the tension in the sample. The measurement of the tension reduction permits a direct calculation of the coupling coefficient alpha through use of the known parameters of a sample. Patents PAT-C1-73-15.6
