Abstract

With this publication we would like to present a high precision triangulation sensor for residual shorts measurement of coiling materials. The sensor is a stand- alone system. A FPGA and DSP are responsible for the timing and reading of the linear CCD-sensors. A microcontroller handles the in- and outputs and does some desired calculating. The basic element of the sensor is a symmetrical arrangement of two laser emitters and their receiving optics. Due to this arrangement we get a stable thermal behavior of the sensor. Furthermore this paper gives some detailed information about the accuracy, resolution and the measuring range of the sensor. One cases of industrial application are listed at the end of this paper.
