Abstract
At least two types of reflective or emissive materials are applied in alternating manner to a pile or other object to be moved. Ultraviolet energy is emitted toward the materials and reflections or emissions therefrom are received by appropriate detector elements which convert the different respective reflected or emitted energy spectra into corresponding electrical signals for use by a processor device to determine the distance and rate which the pile or object is being moved. The calculated information is channeled to a suitable display and a permanent recording device.
