What Is Structured Light Metrology
(SLM)?
SLM is an optical 3D geometric measuring system …
• Based on the principle of triangulation
• Projected structured light fringe pattern
• Digital cameras capture high-resolution images
• 3D coordinates for each pixel are recorded
4 to 11 million data points per scan
• Multi-scans merged to 1 complete 3D image
• Comprehensive post-processing of scan-files 8

What Our Clients Are Saying
"Relative to the results L3I is providing, the current CMM
and optical comparator are only a small improvement
over guesswork.“
K.J., Mfg. Engineer, Orthopaedic OEM
“Studies have proved that the Level 3 Inspections system
and method of inspection for implants is as accurate, or
better than our CMMs. Since the white light scanning
processes have the required accuracy and can cover so
much more of the feature surface, their data is a more
accurate representation of the feature true size and
form.”
I.H., Metrology Director, Orthopaedic OEM
