NAVFAC EXWC requires an automated inspection tool that performs rapid and complete 3D surface measurements and mapping of hand-held sized materials and components.

EXWC requires an automated inspection tool that performs rapid and complete 3D surface measurements and mapping of hand-held sized materials and components. EXWC currently does not have an automated 3D measurement tool. Current inspections of small project parts or specimens are done using manual or digital calipers for width, length, and height, or with an archaic stylus-type profilometer for surface profile and roughness information. These methods are slow and inadequate for critical failure inspections and similar analyses, in comparison to newer scanning technology.
