Abstract

This paper presents an evaluation of three developed parallel registration algorithms for the reconstruction of optical wavefronts. Two practical use cases are considered including high-quality optics generating (i) a plane and (ii) a divergent wavefront. The wavefronts are measured segment-by-segment with a scanning Shack-Hartmann sensor measurement system and are reconstructed by the algorithms. As a benchmark for the comparison of the registration performance, the well-established iterative closest point (ICP) algorithm is used. Results show that the developed registration algorithms attain a registration precision up to a factor of 10 better than the registration precision of the ICP algorithm.
