Abstract

With this paper we would like to present a high resolution linear sensor system. It has been developed for the sheet fabricating industry. The sensor is a stand-alone system. A Digital Signal Processor (DSP), a Field Programmable Gate Array (FPGA) and a Microcontroller (MC) collect and process the data of the linear sensors. The basic elements are six CCD linear sensors. They deliver the required high resolution of the sensor. A multiplexer connects two active linear sensors at a time to the CPU. The switching between the linear sensors is automated by the DSP. Furthermore this paper gives some detailed information about the accuracy, resolution and the measuring range of the sensor. The industrial application is listed at the end of this paper.
