APPLYING SPECKLE-INTERFEROMETRY TO THE SHAPE MEASUREMENT OF MOVING OBJECTS

Andreas Meixner, Andreas Purde, Philipp Kirilenko
Abstract:
Speckle-interferometry is a very interesting group of measurement methods based on coherent light dissipation properties. There are a lot of applications of this effect, but the most interesting one is shape-measurement. It is astonishing that a nearly random structure of speckle image can contain information about the contour of the object illuminated by coherent light. The method is well-known but it is not so popular because of great disadvantage: method needs very good stability of the measurement object and instrument. So this technique was applied only in laboratory for a long time.
In this article we want to present special algorithms and setups which permit applying speckle-interferometry out of the lab – in industrial conditions.
