Paper Abstract

In this work, the authors present a prototype of an adaptive whole-field profilometer based on grating projection. Adaptiveness is achieved by performing the projection of the gratings by an LCD projector. The main features of the hardware and software components of the system are detailed. Profile evaluation, system calibration and certification are also covered. The performances of the instrument, as it emerges from the experimental tests carried out on the prototype version of the system, are discussed.
