ABSTRACT:
An ultra-high speed two-dimensional coordinate transform processor (10) contains layers having conducting lines representing coordinate lines in coordinate systems. Layers in a first set have conducting lines representing a first coordinate system. Layers in a second set have conducting lines representing a second coordinate system and are positioned adjacent the layers in the first set. A signal is applied at a point where lines in the first set intersect. This point represents a point in the first coordinate system. An induced signal is sensed in the layers in the second set at a point where coordinate lines intersect. Since the detected signal will be strongest at the point nearest the applied signal, the intersecting point having the strongest signal will represent the point in the second coordinate system that is the transform of the first point. The processor (10) is faster than conventional coordinate transform methods and is inexpensive to produce. Accuracy may be increased by repeating the processing in a smaller coordinate space.
