Paper Abstract

In this work we present an alternative to design a noncontact profiler using diffractive optical elements in substitution of the traditional optical elements (refractive, reflective). With these elements we have lenses with large numerical aperture and high control of the spherical aberration that is most important in the case of the profilers. In this work, the optical design of a profiler is presented that will be used in a large coordinate measuring machine. The optical design allows to this profiler scan the surface in a continuous way. We also present the algorithms for recovering the form of the surface starting from the date obtained with the profiler.
