The edge break sensor is a compact handheld optical sensor prototype used by operators in the workshop environment to identify micron sized defects, without the time consuming processing of taking a wax mold and measuring that mold on a profilemeter. The system was designed and built in partnership with a large industrial manufacturer and is under going field testing.
The handheld sensor captures surface profile information, it works by projecting a pattern of lines onto the region of interest and then capturing images of that pattern for evaluation in software. Using LED optics, this pattern in created by projecting a LED through a grating (shown in green). The grating sits on a piezo stage which moves to three positions.
A second optical channel includes a camera with a zoom and focusing lens (shown in red). This optical channel collects three images of the grating pattern. These three images are used by a software application to extract profile information.
