Paper Abstract

Moire deflectometry allows one to measure minor angular deflections experienced by light beams, previously collimated, in general,for an easier metrologic decoding. A novel technique is presented aiming at the measurement of curvature radius of polished spherical surfaces. Theoretical studies and experimental results are presented revealing satisfactory agreement, while the sources of errors of the measuring technique are analyzed in detail. The theoretical model is extended to cover the measurement of the focal distance in lenses.
