OCT-Ophthalmoscope scans the human retina in 2 dimensions by a galvo-scanner at high speed and constructs 2 dimensional OCT images (C-Scan images) by detecting the interference signal produced by the measuring light and the reference light. Furthermore, by moving the reference mirror along the optical axis, this system can construct 3 dimensional OCT images. The resolution of the system is 9 microns in the longitudinal direction and 18 microns in the transversal direction.<BR>It enables us by its unique C-Scan OCT images to observe retinal images not only in a one-dimensional intersection but also in the area or the volume and to diagnose or evaluate retinal disease objectively and numerically.
