Remote measurement of distance and thickness using a deflected laser beam.

摘要: A remote optical technique of measuring distance and thickness is described which relies on a measurement the time laser beam deflected at definite speed takes to travel from starting point reference plane final object. Its significant features are high speed, resolution, flexibility with regard range between probe, insensitivity surface properties object, rugged design. It is, therefore, suitable for large variety applications, especially in industrial metrology.
