Laser Trackers 

Are you a manufacturing or engineering company that frequently conducts dimensional inspections of large equipment? Such a process requires the ability to scan more than a single angle and distance simultaneously. The most accurate means of measuring on such a scale is with a laser measurement device or a laser tracker. Here at ETG, we’re one of the leading manufacturing companies, able to produce a wide range of inspection and automation technologies. 

Laser trackers are the perfect tool for use in correctly aligning precision machinery, making them especially useful on production lines or in engineering workshops. A laser measurement device is able to measure to one of two distance meter types – interferometer or absolute distance meter (ADM). This makes it a versatile tool capable of taking the readings you need. Our devices are bespoke, built to your specifications.

What is a Laser Tracker?

Laser trackers, also known as portable coordinate measuring machines, are devices designed for the purpose of dimensional inspection of large equipment. This doesn’t just include stand-alone pieces of equipment but entire assemblies too. A laser measurement device makes measuring large setups, both indoors and outdoors, super-easy. There’s no need to take apart anything, making a laser tracker an excellent time-saving tool in any manufacturing environment. 

Laser measurement devices take precise large-volume measurements of parts, assemblies, and tooling. They possess a large working radial volume and accuracies up to 0.001in. When worked in tandem with advanced software, laser trackers can provide very fast and accurate feedback in real-time. 

Such measuring tools are ideal for precision machine alignments, including: 

  • Turbines 
  • Compressors 
  • CNC Machines 
  • Pumps 
  • And More 

These are common in engineering setups and must be calibrated to ensure they work safely and correctly. Laser trackers are also ideal for field machining, providing real-time feedback of critical geometry controls. These include cylindricity, circularity, parallelism, and planarity. Laser trackers simply cannot be beaten for precise measurements, no matter the circumstances.

How Does a Laser Tracker Help with Taking Measurements? 

Laser trackers measure two angles and a distance. This is accomplished by aiming a laser at a retro-reflective target. This is held against whatever object is to be measured. As the light reflects, its path is retraced. It re-enters the measurement tracker at the same position it left. As the light re-enters, a portion of it goes to a distance meter. This measures the distance from the tracker to the SMR. One of two types of distance meters may exist – absolute distance meter (ADM) or interferometer. 

Distance measurement is an important function performed by a laser tracker. It can be either absolute or incremental. Incremental measurements are obtained with an interferometer and a frequency-stabilised helium-neon laser. The ability to record absolute distance measurements has been around for a long time. ADM has undergone something of a transformation within the last decade. Its accuracy now is easily on par with interferometers. 

ADM offers the added benefit of a ‘point and shoot’ system that’s far simpler to work with. The system measures the distance to the target automatically. This happens even if the beam has previously been broken. Infrared light from a semiconductor laser reflects off the SMR and re-enters the tracker. This is then converted into an electrical signal. The signal is analysed by the internal circuitry, which determines the time of flight. This value is multiplied by the speed of light in air, calculating the distance from the tracker to the SMR. 

Here at ETG, we can manufacture laser trackers that perform both functions. We welcome a discussion to learn more about your requirements. 

Benefits of Using a Coordinate Measuring Machine in Manufacturing 

There are, of course, a wealth of benefits that make investing in laser trackers easily worthwhile. Precision is possible even outside of a controlled environment. Through advancements in laser technology, levels of precision can now be achieved far greater than traditional methods of metrology. As for the benefits, these include: 

  • Versatile Mount 
  • Small, Lightweight Design 
  • Easy to Use 
  • Continuous Point Measurement 
  • Super-Fast Single Point Measuring 
  • Highest Precision and Accuracy 

With the versatile mount, you can position the laser tracker sideways, upside down, or directly on the part being measured. Because laser trackers are often small and lightweight, they are easily portable, making precision measurements in the field possible. 

Laser trackers should ideally be operated by a two-man crew for time efficiency. But in a pinch, they can be operated by a single operator with a computer. Thanks to continuous point measurement, points can be measured continuously. This facilitates tracking critical areas, from thermal growth and shrinkage to moving machinery, without human interference. 

Super-fast single point measuring is made possible because a laser tracker can record 3-axis measurements in a fraction of a second. With additional accessories, data points can be quickly gathered in mass.  

Finally, no other form of measurement outside of a lab is as accurate or precise as a laser tracker. With a real-world tolerance of one-thousandth of an inch, laser trackers are far more accurate than optical measurement, which is often subject to human error and measurement variation.
