Abstract
The Laser Tomographic Scanner LTS is an instrument for contact-free measurement of curvature, thick-ness and incision profiles of the human cornea and of topographic features of the human retina. A line-shaped laser beam is focused onto the eye via special optics. The intensity of the reflected light is detected only if it originates from a very small region around the focal plane of the special optics. Consequently, images with high spatial resolution in all directions are obtained. The line-shaped beam is imaged on the eye with arbitrary direction of the line. At the same time, the focal plane of the special optics is moved periodically. This results in real-time section images of the cornea as well as the retina perpendicular to its surface. System functions are computer-controlled. The instrument is equipped with a powerful computer image processor which produces operator-independent results with high accuracy within seconds.
