摘要

the device makes it possible to carry out prospects, based on the two orthogonal views of an object, by means of three functionally distinct acquisitionprocessing and return; allows the implementation of curvilinee prospects of any kind; also allows the reverse operation, that is, the returnwith an elaborate prospective an object, the two main orthogonal projections. the device also carries out magnification or reduction of produced anywhere in the relations of variables.
