Abstract
A special interferometric technique, which uses light of low coherence length and the Doppler principle, was developed to measure intraocular distances along the vision axis of the human eye in vivo. This laser Doppler interferometry (LDI) technique has been improved to measure the fundus profile and to obtain tomographic images of the human eye fundus, especially in the area of the optic nerve head. A horizontal fundus profile of a human eye between 25 degree(s) nasal and 20 degree(s) temporal consisting of 71 measurement points was recorded in vivo. Furthermore, a vertical scan across the optic disc of the same eye at 13 degree(s) nasal, and from 5 degree(s) superior to 5 degree(s) interior, was carried out in steps of 0.5 degree(s). High accuracy is achieved.
