Interferometric specification of lens (single and doublet) parameters

Three-dimensional analysis of intensity distribution in the interference field of two interfering waves enables one to reconstruct the corresponding wave vectors at each point in space. This has been exploited to specify the radii of curvature, the refractive indices and the thicknesses of a single lens and components of a doublet. The introduced technique is very suitable for lenses of small diameters and short focal lengths.
