Abstract Werden einfache Figuren hinter einem ruhenden Spalt vorbeibewegt, wirken sie in ihrer parallel zu ihrer Bewegungsrichtung liegenden Achse verzerrt und erscheinen bei hoher Bewegungsgeschwindigkeit verkürzt, bei geringer Geschwindigkeit verlängert. Mit Wenzels Projektionsverfahren (durchkreuztes Quadrat; Ellipse; Kamel) werden anorthoskopische Verkürzung und andere Deformationen gezeigt. Hat man im allgemeinen den Eindruck, daß man die ganze Figur übersieht, kommt es am gebrochenen Spalt zum Doppelbild eines senkrechten Balkens.
Simple figures which are moved behind a static slit appear distorted in their axis parallel to the motion direction and appear shortened at high or elongated at low motion velocities. By means of Wenzel's projection method (crossed square; ellipse; camel) anorthoscopic contraction and other deformations are shown. While the general impression seems to see the whole figure a double image of a vertical bar appears when the slit is broken.
