  • Placido projector for corneal topography system
    Publication number: 20100079726
    Abstract: A placido projector for a corneal topography system includes a substrate having dielectric phosphor. The substrate is configured to be activated by electric current and responsive to emit light. A plurality of opaque, concentric rings are formed on the substrate. When the substrate emits light responsive to the electric current, a placido image is projected. The concentric rings can be formed using silk screening or other techniques. The dielectric phosphor can be micro-encapsulated and deposited onto the substrate. The substrate may be an electro-luminance panel. A protective cover is placed adjacent to the substrate to retain the substrate in a predetermined shape. In one embodiment, the placido projector has a frusto conical shape.
