Abstract

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