Fotoelektrisches Weg- und Winkelmeßsystem zum Messen der Verschiebung zweier Objekte zueinander

摘要

The photo-electric distance- and angle-measurement system proposed for measuring the displacement of two objects with respect to each other consists of a number N = n . 4 of photodetectors (1) disposed in a matrix (2) in such a way that the diagonals (a) of the photodetectors (1) are parallel to the diagonal (c) of the photodetector matrix (2), the photodetectors (1), which detect the same phase relation, being electrically connected to each other and their signals being fed to a processing circuit.
