1. Method of operation The Scanner M2D provides 2-dimensional measuring of profile heights. The measured objects may consist of various materials. A laser line is projected onto the target and the distance to several points of the object is measured by triangulation. The Scanner is suitable for the geometric profile recognition and distance measurement. The height (Z-axis) by distance (X-axis) is measured. The result is the contour of the object at the point of measurement. Every 20 ms a complete scan of 283 points of measurement, or every 40 ms a scan with 566 points of measurement is done. The measurement range works from 5...1200 mm (X-axis) and 8...600mm(Z-axis). Please see overview chapter 10.1 Scanner datasM2D/ M2D-W.

1.2 Method of measurement The Line scanner M2D is working according to the triangulation method. The laser line is produced by a pulsed laser diode and line generating optics.The diffuse reflected light from the target is projected onto a 2-dimensional CCDArray (figure 1). The different contour height of the measured object produces deviation of the reflected laser line. This deviation is corrected and linearized trigonometrical. In addition to the distance information (Z-axis), the position of the measured point (X-axis) at the laser line of the line scanner is shown.

1.3 Scanner construction The scanner features a very compact construction since all the linearization and distance measurement is already handled completely from integrated hardware in the scanner itself
