Thus, PS-OCT assesses qualitative characteristics of ocular structures, including arrangement of collagen fibers and presence of fibrotic changes. This chapter describes the basic concept of its technological background, the instrumentation of anterior PS-OCT, and its applications to the field of cornea...

Polarization-sensitive OCT (PS-OCT)1has become an exceptionally useful imaging technique that complements the scattering intensity contrast in standard OCT systems and provides additional diagnostic information and guidance2,3,4,5,6,7. By analyzing the polarizations of the scattered light, PS-OCT ima...
An independent measurement of skin’s optic axis (or birefringence axis) was performed with polarization-sensitive OCT (PS-OCT)51. Both AμT-OCE and PS-OCT measurements revealed very similar orientation of the symmetry axis in the epidermis for all measured subjects. To our knowledge, non-cont...
Polarization-sensitive optical coherence tomography (PS-OCT) allows the recording of depth-resolved polarimetric measurements. It has been reported that phase retardation and local birefringence images can noninvasively detect fibrotic area in blebs after glaucoma surgery. Evaluation of scar fibrosis in ble...
CONCLUSIONS: PS-OCT represents a powerful tool for increasing image contrast in ocular tissues. The observed polarization-scrambling nature of the RPE may be used in diseased eyes to locate the RPE or remains of the RPE definitively in OCT images....
Polarization-sensitive optical coherence tomography (PSOCT) has found many applications in imaging birefringence tissue samples. Polarization-sensitive detection is often implemented by utilizing a circularly polarized incident light and detecting the two orthogonal horizontal- and vertical-polarized interference...
