... National Laboratories. The fringe reflection or deflectometry systems use phase-shifted fringe patterns on a target, and view a reflection of that target in the mirror, in order to map each camera pixel image of the mirror to a specific location on the target. The process used is well documented [ 16...

.... Measuring slope deviations in the parabolic shape of the mirror panels in the accuracy and resolution required for these applications is a challenge as it is not required with the same characteristics in other industries. Photogrammetry and deflectometry are the two optical measurement methods...
