Paper Abstract

Depth-resolved tissue contrast imaging using local polarization properties has been demonstrated in vivo with fiber-based polarization-sensitive swept-source optical coherence tomography. The local birefringence and differential optic axis orientation are calculated with an algorithm based on Jones matrix representation. To enhance the signal-to-noise ratio of images to speckle noise, polarization properties of local sites with thickness of ~ 100 μm are measured. High contrast images of local polarization properties are obtained without averaging. In vivo imaging of the human anterior eye chamber shows the potential of this method to discriminate the birefringent tissues.
