title: Absolute flatness measurement using oblique incidence setup and an iterative algorithm. A demonstration on synthetic data.
abstract: A method to provide absolute planarity measurements through an interferometric oblique incidence setup and an iterative algorithm is presented. With only three measurements, the calibration of absolute planarity is achieved in a fast and effective manner. Demonstration with synthetic data is provided, and the possible application to very long flat mirrors is pointed out.
