Operation of PosCon 3D
The laser line projected by the PosCon 3D is reflected from the surface and depicted on a 2-dimensional optical receiver using the triangulation principle. The required optical image quality is ensured by the specially developed multilens system. The exact distances to the object surface are measured along the laser line and then calculated by means of smart algorithms and powerful coordinate transformation.
The position of an object’s edge, width or gap dimension is transferred over the existing electrical interface. For objects moving along the Y axis, the precise measurement location on the object can be determined by means of sync-input.
The 3 dimensions:
X axis: edge position along the laser line
Z axis: edge position independent of distance from object to sensor
Y axis: edge position along the moving direction by means of sync-input
