Abstract:

A newly developed system of Automatic Contour Display, entitled AUTOCON, receives analog information from a plane of equally spaced data points and simultaneously converts this information into complete contour response surface plots. The system employs a series of analog storage, scanning, and interpolation operations which take a finite number of data points in a plane and, from them, generate an interpolated surface over all these points. As the surface is generated, it is quantized into discrete contour levels which are then drawn on a stored television display for immediate use and on 35-mm film for a permanent record. The present AUTOCON system can accept individual data points at a rate of ten readings per second and will plot a contour consisting of eleven, electronically-identified, distinct, contour levels. The complete system, as well as certain individual portions, is generally applicable to any area of investigation which uses contour response surfaceplots or similar displays as a method of graphical analysis. The systems chief advantage in its present use of stray magnetic field investigations is the elimination of the time required to obtain contour displays of 1 or 2 hr by manual plotting. Author
