Polarization arrangement for visualizing energized structures in human cornea, has camera recording image of cornea, where polarized light from light source e.g. laser, is directed through cornea by beam splitter and is reflected by iris

摘要

The arrangement has a reflection polariscope, whose optical path is arranged coaxial to line of sight, and an electronic or optical camera for visualization and recording an image of human cornea. A light source e.g. incandescent lamp and laser, with a polarizer and a lens, is focused parallel to the optical path. Polarized light from the light source is directed through the cornea by a beam splitter and is partially reflected by iris. A polarization filter is preset to maximum darkness of the reflected light, and a computer takes over and stores image evaluation.
