Paper Abstract

We propose a design of diffractive and refractive optical corrective elements with zooming capability for linearizing the angular scan of a resonant mirror scanner. Considering the symmetry requirements of the refractive element a graded index of refraction and its binary amplitude version are designed based on phase lag (beam retardation due to propagation through an inhomogeneous media). The design takes the beam diameter into consideration making it robust against beam fanning.
