Color-coded methodology for deformable mirrors [PDF]
Optical Engineering, 2006 The paper describes an experimental procedure for the reconstruction of the geometrical parameters of a reflecting surface. The method is based on the projection of a luminous pattern constituted by coloured points. The successive chromatic selection reduces the complexity of the acquired image.
