Measurements of corneal birefringence using phase-shifting imaging polarimetry

摘要

Abstract: Phase shifting imaging polarimetry was applied to measure birefringence of the human cornea in vitro and in vivo. Using computerized polarimeter, two maps representing distribution of the azimuth angle and the retardation are calculated and presented. Investigation of the corneal birefringence could be useful for examining the inner corneal structure and in diagnosis of some corneal pathologies.!7
