Abstract
Optical coherence tomography (OCT) has proved to be a powerful tool for the detection of microstructure in tissue. Label-free tissue differentiation on a micron scale is a promising and powerful technique for segmentation. This Letter describes a technique using a dual-wavelength OCT system to image the eye. We measure the walk-off between interfaces in A-scans, taken at two different wavelengths, to calculate the average group velocity dispersion parameter of each segment of the eye. We present measurements of the dispersion of the cornea and the aqueous humour in rat eyes.
