Abstract	A new geometrical arrangement is proposed to improve performances of optical triangulation. Two scanners in synchronization allow a linear position sensor to be used for surface topography measurement. Besides a large increase in speed of measurement (approximately megahertz), the new geometry allows considerable reduction of the optical head size compared with usual geometries, so the shadow effects are reduced proportionally. It also provides a means to obtain a very large field of view without compromising on resolution. Geometrical analysis and experimental results are presented.
