Imaging Of The Retina By Scanning Laser Tomography

Laser scanning tomography can be used to quantitatively assess the morphometry of the retina of the human eye. In this paper, the confocal imaging mode of the Laser Tomographic Scanner (LTS) is applied to evaluate the thickness of the nerve fiber layer. The contrast of nerve fiber layer images can be enhanced by polarization dependent imaging modes, like Fourier - ellipsometry (F.E.) and differential interference contrast (DIC) imaging. To improve the depth resolution, an active-optical focusing system is employed.
