Algorithms for phase retrieval in spatial phase-shifting interferometry are examined. It is noticed that the classical Carre technique based on four neighbor pixels may introduce shaped phase residuals that affect the accuracy of the reconstruction.

Approach for axisymmetrical asphere polishing with full-area tools

Autor: Mauro Melozzi, Andrea Novi

Publikováno v: SPIE Proceedings.

Aspherics up to 500 nm diameter in optical glass or in ceramic substrates have been fabricated using area- compensated polishing tools and conventional optical shop machines. The tool forms are derived starting from the actual shape of the part under
