The series OSZILLOGRAMME, sometimes also known historically as pendulum oscillograms, was created with the help of an analog computer built by the Viennese physicist Franz Raimann in consultation with Herbert W. Franke, with which the basic arithmetic operations such as addition and subtraction, multiplication and division as well as differentiation and integration could be carried out. This was how the graphic elements were developed, mostly curves, combined in two-channel superimposition – corresponding to the ordinate and abscissa of two-dimensional representations.
A cathode ray oscillograph borrowed from an electronics hobbyist served as the output device. The calculated configurations appeared on its screen in green on a black background. The parameters that determined the shape could be changed interactively and under visual control (series of oscillograms).
Because the oscilloscope's screen was only two inches across, the area captured by the camera was uncomfortably small. Therefore, for a series of these oscillograms, the camera with black-and-white film was moved past the screen in space with the aperture open, which resulted in a typical fanning out of the basic figure (series of pendulum oscillograms).
