UNDERWATER LASER SCANNING

NEWTON LABS

1

NEWTON LABS

Established in Cambridge, Massachusetts in 1990 as an offshoot of the Massachusetts

Institute of Technology (M.I.T.); moved to Seattle in 1995

Specializes in machine vision including line laser scanning, optical automation and robotics

with an emphasis on Automation…“Machines that can See and Make Decisions”

Many of Newton’s projects are the first-of-their-kind in the world

Newton internally manufactures all scanning, machine vision and robotics software and

hardware, including controllers, cameras, lighting, electronics, machine control and

mechanics.

The first Newton Underwater Laser Scanner was the NM200UW developed in partnership

with Exelon, a major U.S. nuclear utility; specifically designed to operate underwater in-

vessel in either PWR or BWR nuclear plants.

Some comparisons with air scanning:

Limited Range-for practical purposes 10 Feet (3 Meters)

Very high resolutions can be produced

Water clarity is important

The Scanner must be held still during the scan for accurate measurements-often more

difficult underwater

4

Crack Detection and Measurement

Surface Scanning-

Human Viewable High Resolution pictures matched to the scan

Measurement – From CAD Models


5

Feature Identification and Measurement

Complete CAD models- With multiple scans


Generally has the same constraints as in air scanning

Newton Scanners produce higher resolutions than most in-air scanners

6

Models:

Functional from 6 Inches (150mm) to 10 Feet (3 Meters)

Depths to 6,000 Ft (2000 Meters)

Resolutions to less than .001 (0.025mm)

Internal Pipe Scanning

Internal Tank Scanning

Models specifically designed for use in nuclear facilities-both from allowed

materials and ease of decontamination

NEWTON PRODUCES VARIOUS MODELS OF

UNDERWATER LASER SCANNERS

NEWTON UNDERWATER LASER SCANNERS

Uses Line Laser technology coupled with a very high resolution camera

8

NEWTON UNDERWATER LASER SCANNERS

All models fully sealed-no moving parts exposed to the water

All models produce high-resolution human viewable pictures along with the scan for ease

of set-up, alignment and human analysis of the scanned object

All cables and connectors rated to 6,000 PSI

Minimum size for rated capabilities

Designed for many mounting methods

Robots

Poles

ROVs

Arms

Communication between the head and controller via GigEthernet

All Head power supplied through the cable from the controller-no other connection to the

head required

Machined Photogrammetry targets on the outer surface

M300UW UNDERWATER LASER SCANNER

Operate with an effective scanning distance of between 1.5 feet (0.46 m) and 10 feet (3 m)

from the target surface

Able to scan an area 9 feet by 7 feet(2.80 m by 2.08 m) with an accuracy of +/-1.0 mils

(0.025mm).

Waterproof to a depth of 320 ft. (100 m)

In addition point cloud data output, there is a human-readable video interface on the

console which displays the scanned area in real time
