Paper Abstract

In this paper, a technique extracting the misalignment information in topographical measurement of the corneal curvature is presented. First, automatic focus is introduced to guarantee system alignment in the direction of the optical axis. Secondly, movement invariant is used to establish the centralized images of a set of rings in the image plane. Therefore, misalignment in the image plane is compensated by adjusting parameters of the optical system.
