25. Confocal scanning laser ophthalmoscopy improvement by use of Mueller-matrix polarimetry.

Author

Bueno JM and Campbell MC

Abstract

A new technique for improving the signal-to-noise ratio and the contrast in images recorded with a confocal scanning laser system is presented. The method is based on the incorporation of a polarimeter into the setup. After the spatially resolved Mueller matrix of a sample was calculated, images for incident light with different states of polarization were reconstructed, and both the best and the worst images were computed. In both the microscope and the opthalmoscope modes, the best images are better than the originals. In contrast, the worst images are poorer. This technique may be useful in different fields such as confocal microscopy and retinal imaging.

26. Adaptive optics scanning laser ophthalmoscopy.

Author

Roorda A, Romero-Borja F, Donnelly Iii W, Queener H, Hebert T, and Campbell M

Abstract

We present the first scanning laser ophthalmoscope that uses adaptive optics to measure and correct the high order aberrations of the human eye. Adaptive optics increases both lateral and axial resolution, permitting axial sectioning of retinal tissue in vivo. The instrument is used to visualize photoreceptors, nerve fibers and flow of white blood cells in retinal capillaries.
