Multi-Purpose Portable Measurement Device

"We propose to develop a simple and accurate field-portable optical device for obtaining critical dimensions for ammunition of size 5.5 mm - 8". Laser-triangulation-based inspections will be performed by passing the munition by-hand through adoughnut-shaped aperture, or in some cases, by passing a probe by-hand near the shell. Inspection results, to consist of dimensional quantities or dimension differences relative to a reference, will be delivered to a local or remote gage database. The3DGage will be a new application of existing nascent surface profiling technology at DCS Corporation. The existing technology has been shown to be feasible but not commercially viable for anatomical surface profiling. However, armament inspection, wherethe surface is relatively smooth and predictable, represents a perfect fit for the DCS technology, which can obtain up to 50,000 point measurements simultaneously over a surface patch. DCS will design the 3DGage hardware and software and a database inDepot Surveillance Record (DSR) format. Experiments to demonstrate feasibility of the core concepts will be performed using existing hardware. System design testing will be performed using simulations of the surfaces and the algorithms. The Phase IOption will prepare for Phase II by obtaining a key component of the prototype 3DGage. The proposed device will be useful in many military surface profiling applications where the object is rigid and smoo
