28 September 2016 Accuracy and sensitivity analysis of the conical null-screen based corneal topographer
Author Affiliations +
In every optical testing method, the time taken to process data, the precision of the results and the sensitivity are among the most relevant aspects to be taken into account when the viability of its implementation is been under consideration. An accuracy and sensitivity analysis of a topographer based on a conical null-screen with a semi-radial distribution of targets is presented. On the other hand, we proposed a custom evaluation algorithm in order to reduce the time in the calculation of the normal to the corneal surface. Finally, we perform some corneal topographical measurements.
