Problem Introduction

Ophthalmologists would like to have an accurate representation of the anterior corneal surface. This representation is used to design contact lenses, eyeglasses, and to reshape the cornea via surgical procedures to improve eyesight. Since we are unable to measure the cornea with physical objects, ophthalmologists need a remote sensing technique to produce the desired representation of the corneal surface. The field of study related to this endeavor is known as corneal topography.

The goal of this project is to develop such a technique and determine the reasonableness of our technique. Current techniques project a grid pattern onto the cornea and then photograph the reflection of this grid pattern. This produces a distortion of the original grid pattern. (See Figure 1.)
