Simulation Chamber for a Modified Senarmont Measurement Method

In modern manufacturing techniques automated, noncontacting, and on-line measurements of the optical path difference and the birefringence of moving anisotropic specimen (fibres, films) may be carried out free from false colours and rapidly even at very high path differences. A modified Senarmont measurement method is applied. A simulation chamber will be used to investigate problems still remaining. In particular, the effect of the torsion angle of the films, the influence of an angle in the optical path during the noncontacting measurement at fibres, and the effect of position deviations of fibres on the optical path difference and the birefringence have been tested.
