Reflective metal: missing or false points

Polished stainless, chrome, machined faces. Large dropouts or phantom bumps in the cloud

Published measurements Root cause: Specular reflection LUC-VISION™

Why it fails, and why we are not bound by it

Structured light assumes that the surface scatters the projected pattern back. A mirror does not. It sends the pattern elsewhere and leaves dropouts. Interreflections between parts also create surfaces that do not exist. FMCW reads the frequency difference between the return and the local oscillator, not the deformation of a pattern. Specular returns therefore carry usable range information.
