  • Method for determining absolute spatial coordinates of at least one point on a reflecting surface
    Patent number: 5900924
    Abstract: By localizing a location D on an optical axis, a virtual image is determined and compared with a measured virtual image. Using an iterative method, a location D can be shifted until the calculated and measured virtual images coincide and these data can then be used to determine an absolute spatial co-ordinate for a point on the surface. This method can be used, for example, in charting the surface of the cornea of an eye which has a reflecting film of tears.
