| titleOfInvention | Process and device for determining the topography of a reflecting surface |
| abstract | PCT No. PCT/EP94/00027 Sec. 371 Date Jul. 21, 1995 Sec. 102(e) Date Jul. 21, 1995 PCT Filed Jan. 7, 1994 PCT Pub. No. WO94/16611 PCT Pub. Date Aug. 4, 1994A process is disclosed for determining the topography of a reflecting surface. A projection pattern is projected onto the surface and a thus formed mirror reflection pattern is detected and evaluated. In order to improve the correspondence of the structures of the reflection patterns with those of the projection patters, the projection pattern contains recognition marks which individualize the continuous black/white or light/dark areas. A color mark or hatching is particularly advantageous. In order to apply the projection pattern on the cornea of the eye (3), a projection body (17), for example a hollow cone, is used, with transparent rings (19) arranged in this side wall (18) and surrounded by a ring-shaped light source (20). A color video camera (26) is used as detector. |
