Micron-resolution structured light scanner for AM part
This technology is a high-precision 3D scanner that uses structured light — projected patterns of light — to create extremely detailed digital maps of small object surfaces, with resolution down to 2 micrometers (about 50 times finer than a human hair). It uses two cameras working together to capture images of a target object, then mathematically reconstructs the 3D shape from how the light patterns deform across the surface. The system is designed for scanning small areas (50mm x 50mm or less), making it purpose-built for inspecting or documenting tiny, intricate parts. The primary application described is quality control and surface verification in additive manufacturing (3D printing), where small defects or dimensional errors in printed parts are difficult to detect with standard tools.
What you could build
A bench-top or in-line 3D surface inspection system for manufacturers of precision additively manufactured components — such as medical implants, aerospace brackets, or microelectronics housings — who need micron-level dimensional verification without expensive tactile CMMs or electron microscopy.
Who in Virginia should care
Virginia defense and aerospace manufacturers, as well as biomedical device companies in the Northern Virginia/Richmond corridor, using additive manufacturing for precision parts would be natural early customers or licensing partners.
Readiness: Lab validated
Concept — described but not yet demonstrated. Lab validated — supported by experimental results in the patent. Prototype likely — the text describes a built, working embodiment.
Readiness is inferred from the patent text, not from a lab visit.
