Analysis of the systematic and random errors in the conical corneal Null-Screen Topographer

摘要

In this work we describe how to perform virtual experiments by deforming our ideal device with translations and rotations of each component, then we determine which are the minimal deformations that can be detected (sensibility) and how much does they affect the results of the measurement (sensitivity), a necessary endeavor since systematic errors due to misalignment of the components may lead to poor performance of optical systems, especially those used to measure optical components. The simulation of the passage of light is computed using a system of equations obtained from the vector reflection law.
