Abstract

The paper presents the polygon scanners used for industrial, dimensional measurements. The characteristic parameters and functions of the measuring system are ascertained: the scanning function and velocity, the two pairs of characteristic angles, the duty cycle and the two-parameters functioning characteristic. The possibilities of obtaining a one-parameter functioning characteristic are explored. A rigouros mathematical analysis of these subjects is performed, including the discussion of their diagrams, obtained not numerically, but analythic. An experimental validation of these results has been presented in a previous study. The results obtained for the optical scanner are quit general, and they are also valid for other applications of the laser scanners, besides the particular one considered in the paper. In order to complete the designing calculus of the system, the migration functions that characterize this type of scanning head, the polygon, are defined, ascertained and used, the designing steps being thus fulfilled.
