Measuring Principle

Generation of straight fringes in the coordinate plane. Recording of deformed fringes on the object (reflection). Analysing surface angles as well as other analysing of curvature and 3D form.

Obtained Data

Angle of the normal surfaces	=> locale curvature	=> 3D Form (height)

Area of Application

In general measurement of all reflective surfaces.

Examples

Liquids	(plastic) Lenses	Lacquer (orang peel paint effect)

Technical Data

Measuring Examples

• Formvermessung an reflektierenden Oberflächen - Reflektoren für Autolampen
• Strukturvermessung an reflektierenden Oberflächen - Bleche und Lacke ( Low Resolution)

Software

• FringeProcessor
