Laser Ultrasonic Thickness Measurement

The basic components of a laser ultrasonic system are a generation laser a detection laser and a detector.

Laser ultrasonic thickness measurement. The laserlinc ultragauge series of ultrasonic devices measure wall thickness or layer thickness and concentricity of clear or opaque plastic rubber glass and metal products like tubing hose pipe insulated wire and cable. Laser ultrasonics uses lasers to generate and detect ultrasonic waves. In some cases ultrasonics can measure diameter and ovality eccentricity. Thickness measurement in 1 2 steel.

For measuring material thickness the process involves the following. In the laser ultrasonic testing system illustrated schematically here the small fiber coupled measurement head is placed near the part to be evaluated and the remote base station contains all the support equipment. Laserlinc uses ultrasonic frequencies from 2 25 mhz to 50 mhz. Spacing of echoes gives thickness to high accuracy.

Lasus today offers a standardised wall thickness measuring system for all the forming stages in the hot production of tubes. The measuring principle is the proven ultrasonic technology which has now been further developed for use even at high temperatures by means of laser induction and detection. It is a non contact technique used to measure materials thickness detect flaws and carry out materials characterization. Hence if any corrections need to be made they can be made immediately.
