Device for contactless measurement of wall thickness distribution of transparent material, has light source, image recording unit, processing unit, and rotating unit swiveling around vertical axis

摘要

The device (1) has a light source (3), an image recording unit (2), a processing unit (5), and a rotating unit (4) swiveling around a vertical axis (Y). The light source, emitting light (L) on a side opposite to the image recording unit, is arranged with an angular misalignment in a direction of the image recording unit such that the light strikes on the image recording unit during screening of a transparent material (M). The transparent material is arranged in rotating manner at the rotating unit between the light source and the image recording unit. An independent claim is included for a method for contactless measurement of a wall thickness distribution of a transparent material.
