... applications. SOFAST can be used for facet analysis during development. However, the real payoff is in production, where complete analysis is performed in about 10 s. With optimized coding, this could be further reduced. optical characterization dish optics facet slope error deflectometry fringe...

... lens for the camera (due to field of view constraints). Switching camera lenses during the analysis would have introduced a host of additional variables and was avoided. SOFAST and other deflectometry tools mentioned here provide extensive facet...

.... 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...
