Abstract
The local radius of a reflecting surface can be measured by imaging a grating in a F-Theta- Setup. The radius is determined by measuring the grating period. That can be done in a moire technique where the reference grating is a moire itself. The reticule can be scaled for direct reading of the radius by using the properties of the secondary moire.
