An interferometric method for quantitative evaluation of the magnitude and direction of birefringence of an arbitrarily oriented birefringent sample is developed and presented. The analysis shows that full-field analysis of a spatially varying birefringence is possible by suitably combining several interferogram frames obtained by varying the polarization parameters involved. The preliminary experimental result for a uniformly birefringent sample with a known direction of birefringence is presented. © 2015 Society of Photo-Optical Instrumentation Engineersread more

In vivo birefringence and thickness measurements of the human retinal nerve fiber layer using polarization-sensitive optical coherence tomography
TL;DR: A fiber-based PS-OCT setup that produces real-time images of the human retina in vivo, coregistered with retinal video images of a healthy volunteer's location, shows that the nerve fiber layer located inferior and superior to the optic nerve head is more birefringent than the thinner layer of nerve fiber tissue in the temporal and nasal regions.

Two-dimensional birefringence measurement using the phase shifting technique
TL;DR: In this article, a phase shifting technique for the measurement of a two-dimensional birefringence distribution is described and discussed, and the results and procedures for measuring such a bireringence distributions of optical components such as a calibrated Babinet-Soleil compensator, a lens, and a roof prism are discussed.

Automated detection of foveal fixation by use of retinal birefringence scanning
TL;DR: Foveal fixation was monitored in normal subjects remotely and continuously by use of a noninvasive retinal scan and the detected signal was predominantly 88 Hz during central fixation and 44 Hz during paracentral fixation.

Phase-shifting method with a normal polariscope
TL;DR: A new phase-shifting method that can be applied under these constraints is proposed and it is shown that four phase steps are sufficient to determine both the isoclinic and the isochromatic parameters.
