MORENO OLIVA, V.I. et al. Reconstrucción 3D de la sagita de una superficie en rotación. Rev. mex. fis. [online]. 2005, vol.51, n.6, pp.636-640. ISSN 0035-001X.

An instrument of optical contact is described to obtain the values of zagita in 3D of concave and convex nonreflecting surfaces. The system measure the zagita imaging a thin variable slit over the surface test. To obtain 3D information the instrument is translated in X direction and the surface test is rotated a constant angular velocity. With this system is reached a resolution of 2.5μm in Z and 1μm in X.
