White Light Scanner Resolution

A scan can be achieved in about 2 seconds and the scanning area is also quite large.

White light scanner resolution.

The white light scanners which are mounted on a tripod capture more than 1 000 000 points per second. As described here white light interferometry is a non contact optical method for surface height measurement on 3 d structures with surface profiles varying between tens of nanometers and a few centimeters. In general you can increase the quality of a black and white scan by increasing the resolution. This allows us to capture scan measurements in an area up to 18 feet in diameter and at a rate of nearly 500 000 points per second.

Gom s atos systems which have since evolved to utilize the more advanced blue light technology were using white light commercially as early as 1995. Creating the 3d image. Most objects can be scanned in mere minutes and quickly integrated into your preferred software whether for reverse engineering computer aided design or 3d printing sorfware. Just like laser scanners structured light scanners are extremely accurate and offer a high resolution.

Instant mesh ready to use files. White light scanners are usually tripod mounted where a fringe pattern is generated by scanner s projector and is laid over an area at a time over the scan object. Structured light scans can be so accurate that this process is a popular choice when a near exact virtual model is required. It is often used as an alternative name for coherence scanning interferometry in the context of areal surface topography instrumentation that relies on spectrally broadband visible.

Figure 1 illustrates how your choice of resolution affects the final image. It would also work for scanning larger objects at high resolution if time were not an issue. With structured white light scans are typically accurate up to less than 0 001 of an inch. The go scan 3d is our fastest technology.

Within the scanning time the fringe is modified in width and phase and the 3d scanner extracts the 3d coordinates from calculating the returned patterns. This is less true of laser scanners. The blue light scanner s software combines multiple scanned images into a 3d surface image that can be stored rotated expanded and otherwise examined to evaluate a part or assembly. Structured light can capture a denser point cloud that typical laser scanning.

The laser scanners are mounted on a romer arm or tracked with an ndi optical system. White light 3d scanning works by projecting the line shadows from a 2d lens to a 3d surface. 3d white light scanners. At low resolutions such as 75 ppi black and white scans can exhibit serious artifacts including broken lines and aliasing which refers to the jagged staircase pattern on curved or diagonal edges.

For large scale non interferometric measurement systems see. High measurement rate up to 1 500 000 measurements s 99 white light scanning lines. A white light scanner is a device for performing surface height measurements of an object using coherence scanning interferometry with spectrally broadband white light illumination.
