More Information
Summary:A system and method for profile measurement based on triangulation involves arrangement of an image acquisition assembly relative to an illumination assembly such that an imaging plane is parallel to a light plane (measurement plane defined by where the light plane impinges on the object), which supports uniform pixel resolution in the imaging plane. The image acquisition assembly includes an imaging sensor having a sensor axis and a lens having a principal axis, wherein the lens axis is offset from the imaging axis.
