Evaluation of Surface Shape and Refractive Index of a Transparent Plate Based on Light Path Analysis
Many practical tasks in industry require the simultaneous determination of 3-D shape and refractive index of a transparent object. We have formulated an approach to evaluating the surface shape and refractive index by light path analysis. The effectiveness of the proposed method was confirmed from experimental results.
