Structured Light Scanning works by projecting light onto an object and measuring the way that light reflects back. By taking many "pictures", the 3D scanner can reconstruct a 3D mesh of what it scanned. By stitching together multiple meshes, a computerized model can be made of a real part.
Process Name
Structured Light Scanning
Applications
Digitization of legacy designs created before CAD, reverse engineering, part repairing.
Advantages
Much quicker than measuring features on a part by hand, can capture features that would be very difficult to measure by hand like compound sweeps and curves
Limitations
Has difficulty capturing shiny or dark surfaces, and may require matting spray. Deep holes (>0.5 x diameter) will not be fully captured.
Specifications
