Industrial metrology is a key challenge in all fields of activity when an accurate dimensional control is required to guarantee norm adequacy of product specifications and to aim at ``zero default'' quality. Current systems are based on such technologies as stereoscopy, photogrammetry, structured light projection, active triangulation or time-of-fly methods. In general, these systems are task-specific, bulky, fragile and cannot operate in hostile environments. Moreover, they suffer from a geometrical limitation because of a death angle in which no measurement can be performed.In this thesis, a new probe, called conoscopic scanner and based on the use of spatially incoherent light, is presented. It offers such unique features as (i) ability ...
