Optical Measuring Arrangement and Optical Measuring Method

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention discloses an optical measurement arrangement and method for contactless scanning and detection of surfaces, treatment zones, and process areas on workpieces. It employs one or more sensors that use the principle of dividing incident electromagnetic radiation into diffracted and reflected components at a specially designed optical interface. This setup allows for precise, non-contact measurement of the position and characteristics of illuminated spots and emission sources, such as those found in laser processing or quality control environments.

Patent Abstract

The invention relates to an optical measuring arrangement (10) for the contactless optical scanning and/or detection of surfaces and/or treatment zones of workpieces and/or processes. The optical measuring arrangement (10) comprises at least one angle of incidence sensor (30) which is positioned in the beam path of electromagnetic radiation emitted by a measuring point (12) or emission source. Said angle of incidence sensor (30) has at least one body (26) which is arranged in the beam path of the electromagnetic radiation emitted by the measuring point (12) or the radiation emission source and is at least partly permeable to the electromagnetic radiation. The optical angle of incidence sensor (30) comprises at least one exit point acting as an interface (6) for splitting up the electromagnetic radiation into diffracted and reflected portions of the electromagnetic radiation.
