Abstract

Fresnel lenses are attractive for scanning systems because they provide optical power from a thin lens. Thin lenses are less expensive to manufacture via injection molding and have less chromatic dispersion. However the discontinuous structure of the Fresnel zone transitions may generate undesirable diffraction effects. Matlab™ code has been developed both for designing several types of focusing Fresnel lenses and for analyzing the diffracted optical field at the image plane. The concept of phase-matching was explored as a technique of ensuring that light waves from the zone structures constructively interfere at the image plane.
