Abstract

Many electromechanical devices require positional feedback information. The system should be capable of providing a high resolution over long distance and at the same time be capable of implementation at a low cost. Some devices, such as wire matrix printers, use emitters that feed back pulses at regular distances based on signal planes crossing each other. Other printers use optical emitters, while still others do not use emitters at all. A problem with traditional emitter technologies is that high resolution occurs at a very high cost and, regardless of the cost, the resolution rapidly approaches a finite number based on the optical or copper etching capabilities.
