Editor’s Pick: New Optics, Electronics Speed Portable Scanning

Tony LockwoodDear DE Reader:

Even with a portable measuring arm, using a laser scanner for point-cloud inspection, reverse engineering or whatever job the boss has you doing can be a tedious affair. You might have to warm up and calibrate the device. Maybe you wrangle it into tight spots, reference it, connect all sorts of cables and what have you. And then you poke along scanning at less than light speed. Today’s Editor’s Pick of the Week looks at a portable laser scanning system that sounds like it has done away with a lot of that pesky stuff.

At a Glance: RS4 Scanner

  • New scanner for the portable ROMER Absolute Arm with Integrated Scanner.
  • New optics and electronics; new profile helps you scan deeply into hard-to-reach cavities.
  • Wide laser stripe of up to 150 mm that can capture 752,000 points per second.
  • Offers a 100Hz maximum scanning rate; 0.028 mm accuracy.
  • Requires no warm-up or referencing.

Your skinny here is that Hexagon Manufacturing Intelligence has a newly engineered laser-scanner for its ROMER Absolute Arm with Integrated Scanner. The ROMER Absolute Arm is an all-purpose portable measuring arm. It comes in six sizes with measurement volumes with diameters between 2.0 m and 4.5 m. You can get optional Feature Packs for functionality like WiFi and battery power.

The new scanner for the ROMER Absolute Arm with Integrated Scanner is the RS4. It’s a turn-on-and-go system. No referencing or warm-up required. It’ll scan regular and complex surfaces as well as problem surfaces like carbon fiber. It has an adaptive laser power feature so that you can scan multicolor surfaces without fuss. It gives you visual, acoustic and haptic feedback. The RS4’s design coupled with the ROMER Absolute Arm’s range of movement should make it easy enough to snake into tight spots and get accurate data.

Still, the neat thing about the RS4 is that it scans more than 60 percent faster than its predecessor. What does that mean? Well, it deploys a wide laser stripe of up to 150 mm, which is about double the size of the earlier model. That means you can capture up to 752,000 points per second. The maximum scanning rate is 100Hz, and accuracy is 0.028 mm. And that means you should be able to get the job done more quickly than you imagine.

Hexagon Manufacturing Intelligence is now fitting its new RS4 scanner on the ROMER Absolute Arm with Integrated Scanner. You can get the RS4 model as a retrofit, too.
