Abstract
Aim. To establish the relationship between the intensity of light passing through a loaded sample and the state of polarization and the magnitude of the acting force, taking into account induced polarization dichroism.
Methodology. An experimental study of the azimuthal dependence of the intensity of monochromatic light passing through a transparent sample subjected to uniaxial compression was conducted. Theoretical models were constructed and analyzed, accounting for possible deviation of the sample's optical axis from the vertical and induced polarization dichroism.
Results. Based on the study of the azimuthal dependences of light intensity under various loads, the value of the photoelasticity coefficient of the studied sample and the absorption coefficient due to induced anisotropy were determined.
Research implications. The analysis carried out showed the need to take into account, in addition to the birefringence caused by the load applied to the sample, both induced polarization dichroism and the possible deviation of the optical axis, for a complete analysis of the azimuthal dependences of the light intensity.
