A structured-light 3D scanner is a non-contact scanner that utilizes a camera system, a single light source, and projected light patterns to take measurements of an object’s surface height and obtain important 3D data and produce a 3D scan. 

The resulting high-resolution 3D scans can be used to create an accurate 3D model for dimensional inspection, quality assurance (QA), quality control (QC), prototyping, manufacturing, or reverse engineering (RE). Structured light scanners are capable of optically measuring anything from blade turbines used on airplanes to orthopedic medical devices, anywhere non-contact metrology is needed.

Structured light technology is highly accurate due to the fact that scans are taken at multiple angles using multiple points of light using projected light patterns, which deform as they interact with the surface of the object.

Compared to technologies like 3D laser scanning, where a single laser point is used to scan an object, structured light scanning and the use of light patterns allow for simultaneous, accurate measurements to be taken, decreasing the total scanning time. So, not only does it provide high accuracy, structured light also works at high-speeds.

But why is measuring the surface of an object important? It’s helpful because a precise point cloud can be generated when the surface is scanned using 3D scanners or photogrammetry software. Point clouds are used for creating 3D computer-aided design (CAD) models for manufactured parts, as well as for metrology and inspection purposes.

The use of point clouds allows for improved quality control workflows, giving engineers, researchers, and even the casual enthusiast the chance to create more efficient ways to shape and produce parts while increasing speed and accuracy. 

Due to their speed and accuracy, 3D structured-light scanners are a highly versatile tool used in both research and manufacturing settings. They offer a high-quality alternative to 3D laser scanning systems, which are prone to disruption or interference based on the method of inspection.

Structured-Light Scanning Methods, Illumination, & Applications

There are some important differences between white light scanning and blue light scanning that ought to be considered when acquiring an optical scanning device. Here, we cover the basics of fringe pattern, light source, and go over the pros and cons of the structured-light scanning process. 

Projected Light Patterns

The basic function of a structured-light scanner is straightforward. The scanner’s lightsource projects a pattern of light from a 2D lens onto a 3D object, which distorts as it interacts with the object’s surface. It is also possible to use two laser beam points to intersect.

The distortion that occurs is filmed using multiple, sophisticated cameras, capturing even the slightest displacement in light. The scanned distortions are directly converted into 3D coordinates. These coordinates are used to generate a model of that particular area on the object’s surface. The object is then rotated, repeating the process, and the scanner records the next visible section of the object.

Once the entire object is scanned, the data is processed by scanning software, using a method of triangulation in which the depth and surface information of the object is determined. The multiple scans are then cleaned up and stitched together, forming a highly-detailed, digitized three-dimensional model. This last step in the scanning process is referred to as post-processing. Both white and blue light scanners use the same technology, but the type of illumination differs.


White Light

White light scanners perform surface height measurements of an object using white light as a source of illumination. These devices can be used on a camera mount, tripod, or robot to create a point-and-shoot style workflow that minimizes any set-up or programming time.

White light scanning is the predecessor to blue light scanning, and is typically more accessible than blue light, however, blue light scanning results has proven to be more accurate and less susceptible to the effects of transparency or reflections.


Blue Light

Structured-light scanning systems that operate using LED bulbs, or blue light, are referred to as blue light scanners.

These are considered to be more accurate than white light scanners, and provide an enhanced experience compared to white light scanning. The two types of light are used in similar situations; however, blue light offers a higher output of quality through increased precision and accuracy.

Blue light scanners yield better results due to the fact that LED has a narrower wavelength, whereas white light is a combination of all the colors on the visible spectrum. Blue light is able to filter any interference from ambient light much more effectively than white light is. It is safe to say that blue light scanners offer enhanced capabilities, however, white light scanners are also capable of highly-accurate measurements.


3D Structured Light Scanner Applications

Structured-light scanning systems provide ease of use, accuracy, and a number of advantages compared to other traditional methods of 3D scanning. Some applications of structured light 3D scanning include:

  • Dimensional measurements used for the reproduction of parts, defect detection, repairs, and further quality assurance.
  • Reverse engineering (RE) of objects, used to produce CAD data in particular.
  • Automated optical inspection in high-volume manufacturing and assembly.
  • Volume measurement of complex, engineered parts.
  • Recovery of damaged or worn parts.

Lease Structured Light Systems & Scanners with Excedr

Product design, reverse engineering, and QA/QC all rely on accuracy and proper time management, accuracy and speed that structured light 3D scanners can provide. The fewer errors you make during production, the faster you get a product to market. All of this can help your business save money, increase your competitive advantage, and improve your profit margins.

However, if buying 3D optical measurement equipment is an issue, know that you have some alternatives! Our structured light scanner leasing program can get you the scanners you need without the costly downpayment upfront.

Request a structured light scanner lease estimate today or simply get in touch with us to learn more about our program and the costs of leasing.

Additionally, if you’re interested in other scanning solutions, such as laser scanners or laser trackers, we can help you with that as well. Our leasing options are not static, and we can source virtually any type of equipment for you.

Operating Lease

This off-balance sheet financing structure provides three options at the end of the term. The lessee has the option to return the equipment to the lessor, renew at a discounted rate, or purchase the instrument for the fair market value. Monthly payments are also 100% tax deductible which yields additional monetary savings.


If you recently bought equipment, Excedr can offer you cash for your device and convert your purchase into a long-term rental. This is called a sale-leaseback. If you’ve paid for equipment within the last ninety days, we can help you recoup your investment and allow you to make low monthly payments. This also frees up money in your budget rather than tying it down to a fixed asset.
