Leica T-Scan Technology Used to Capture Famous Artifact from the Civil War Ironclad USS Monitor
The Metrology Division of Leica Geosystems has announced their newest Local Positioning technology, the Leica T-Scan product, was used for the high-precision surface data capture of a famous artifact retrieved from the Civil War ironclad USS Monitor The historic anchor was the first major relic recovered by the National Oceanic and Atmospheric Administration (NOAA) from the Monitor National Marine Sanctuary, east of Cape Hatteras in the Atlantic Ocean

The Mariners' Museum (Newport News, VA) is home to hundreds of artifacts and archives from the Monitor.
Leica Geosystems joined hands with the Mariner's Museum and MAGLEV (McKeesport, PA) for this data acquisition project resulting in an accurate 3D digital replica of the anchor.
At 7000 points per minute, the hand-held scanner allowed the team to capture the 3D object in a fast, unfettered manner.

The Leica T-Scan works in tandem with the Leica Laser Tracker, a portable coordinate measurement system (PCMM) used for industrial measurement and inspection applications.
Metrologists can use the Leica T-Scan to work in measurement volumes of up to 30m.
The operator can digitise both small and large objects, and gather millions of points in just minutes with an accuracy of better than 100 microns.
Complete 3D coverage is made easy by the tracker's ability to be relocated to various vantage points and collect multiple data sets in the same coordinate system.
Senior metrologists from Leica Geosystems and MAGLEV gathered at the Mariner's Museum for the two-day endeavor.
The Leica T-Scan works so intuitively that the Museum workers each had a chance to use the device and capture digital data from the anchor.
This surface data will form the foundation of a highly detailed 3D computer model that can be used for measurement, documentation, and archival records.
This digital record of the anchor's construction can also be used to monitor the anchor's condition, and to reproduce physical prototypes for merchandising and exhibit purposes.
The Mariner's Museum has worked conjointly with NOAA and the U.S.
Navy to obtain more than 1,100 artifacts from the Monitor, including the anchor, steam engine, propeller, and revolving gun turret.
The Mariners' Museum and NOAA are working toward constructing and opening a new USS Monitor Center in March 2007.
A full-scale replica of the Monitor warship will serve as the dynamic focal point of the Center.
The results of Leica Geosystems data acquisition work, and other scanning projects, will directly contribute to the Museum's ability to create exciting exhibits and rich visualisations of these historic artifacts.
Using the Leica T-Scan, reverse engineering and inspection processes now require less time for set-up and object preparation.
Leica's Universal CMM solution combines laser tracking functionality with probing and scanning capabilities in the largest measurement volume.
No competitor in the metrology marketplace brings this dimension to the shop floor.
For more than two decades, the Leica Metrology Division has served the needs of the aerospace, automotive, and general engineering industries.
