This fully dimensional CAD model of an underwater jet pump bracket bolt was rendered in 3-D software by combining
point clouds from consecutive scans at different positions. Areas of greenish coloration indicate corrosion.*
Both the M200UW and M300UW operate by laser triangulation. The projected laser line sweeps the target surface and the high resolution camera, centered on the target, captures and records any deformation of the line as a point cloud, enabling precise dimensioning using 3-D software. Although specifically designed for use in fresh or salt water, these versatile scanners can also operate in air.
- The M200UW is able to scan a target as close as 6 in. (150mm) and out to a distance of 3 ft. (0.9M) for a scan coverage area of 2.1 ft. x 2.9 ft. (64 cm x 88 cm). The M200UW system measures underwater targets up to an accuracy of +/-.0004 (0.01mm) (after processing with third-party, 3D software**)
- The M300UW is able to scan as close as 1.5 ft. (0.46 m) and out to a distance of 10 ft. (3 m), where its field of view is an area nine feet by seven feet (2.80 m by 2.08 m). The M300UW system measures underwater targets up to an accuracy of +/-.001 in. (0.025 mm) (after processing with third-party, 3D software**)
- Both scanners are designed to scan and capture much larger target areas by combining several point clouds together to form larger composites.
- Operators may select from several levels of scan quality via the user interface. The shortest, most coarse scan takes 15 seconds, while the longest and most detailed takes approximately three minutes.
- Laser light color is maximized for water penetration. The specific wavelength of the laser allows for highest possible efficiency underwater transmission.
- The scanner camera only accepts the specific color produced by its own laser and LED lights, greatly reducing any contamination from stray light in the scanning environment; thus making the M200UW relatively immune from any other underwater work lights during operation.
- In the visual observation mode, the LED ring array on the head illuminates the area and the camera transmits a monochrome image to the control console screen to assist the operator for optimum positioning and on-site analysis.
- The control console powers and communicates with the scanner through the cable via low-voltage DC power and signals, and the camera sends scan results up via Gigabit Ethernet.
- All data is permanently stored for later analysis and study via in-console solid state drive and/or transferred by USB to a flash drive.
