NEW SOLUTIONS FOR POLARIZATION-SENSITIVE OPTICAL COHERENCE TOMOGRAPHY

The work is a development of the studies presented in [1] on the reconstruction of the corneal structure of the eye, using a modified Mach-Zehnder interferometer, equipped with a polarization modulator and a feedback loop.A distinctive feature of this approach is the consideration of the depolarization of the object signal, which arises due to scattering on epithelial cells and keratocytes of the cornea.The introduced ratio of polarized and depolarized intensities enabled the evaluation of the depolarization effect on the object signal, while the proposed experimental solution allowed for an increase in the accuracy of eye structure reconstruction by 22.84%.Elimination of the "noise" vertical component of the object signal, caused by the depolarization of the input horizontally linearly polarized wave, led to the successful reconstruction of the corneal structure from the vertical channel of the interferometer, as demonstrated in this study.
