Paper Abstract

We found that any uniform stressed area in loaded birefringent material observed in a polarized, white light shows an extinction effect for different light wavelength (lambda) . The shape and spectral position of the fringes depends on the value of the applied force and the type of material. The new effect is like the Mueller fringes, but we have observed the changing of the material birefringence rather than the thickness. We have studied the interference effect for a `disc-like' whole cylinder of different materials loaded by uniaxial forces acting along the diameter. The cylinder posses a uniform stress area in its center and that area is under study. The measurements were made for various materials on a computer aided spectrometer, (specially constructed for the research), under different loading conditions. The results of the measurements are discussed and compared with theoretical predictions. The effect can be utilized for construction of an optical force sensor.
