Abstract
Moire deflectometry, a method for ray deflection mapping, is described. Its use in lens testing for determining properties such as surface microstructure, radius of curvature, thickness, aberrations, and OTF (optical transfer function), is demonstrated. Unlike interferometry, moire deflectometry is a ray tracing technique, and therefore the analysis of three dimensional objects is greatly simplified. Although the ray tracing approach to optical systems is much older than wave theory, moire deflectometry seems to be the first attempt to apply ray tracing methods systematically to optical metrology. The technique is fully quantitative, interferometry compatible in accuracy, and has the additional advantage of tunable sensitivity.
