Title: PIPE WALL THICKNESS MEASUREMENT
Abstract:
A method of measuring a wall thickness of a pipe can include optically detecting vibration of the pipe, and computing the wall thickness of the pipe, the computing being based at least partially on the optically detected vibration. Another method of measuring a wall thickness of a pipe can include optically detecting temperature of the pipe, and computing the wall thickness of the pipe, the computing being based at least partially on the optically detected temperature. Another method of measuring a wall thickness of a pipe can include optically detecting vibration and temperature of the pipe, and computing the wall thickness of the pipe, the computing being based at least partially on the optically detected vibration and temperature.
