In today's fast-paced world of technology, handheld 3D scanners have become increasingly popular. They offer a convenient way to create detailed digital models of real-world objects, making them a valuable tool in the fields of design, engineering, and various other industries. In this blog post, we'll explore the world of handheld 3D scanners, offering you a thorough comparison of the different models and features to make an informed decision about which scanner suits your needs best.

Understanding 3D Scanning Technologies

To truly appreciate the differences between the various handheld 3D scanners available, it's important to understand the underlying technologies at play. Typically, handheld 3D scanners use one or a combination of the following scanning technologies:

1. Structured Light (SL):This method projects a series of light patterns onto the object being scanned. The scanner captures the distortion of the light pattern as it reflects off the object, allowing it to reconstruct the original shape in 3D.

2. Laser Triangulation (LT):In this process, a laser beam is projected onto the object being scanned, and the scanner measures the angle of incidence of the laser beam as it reflects off the object. This information is then used to create a 3D representation of the object.

3. Time of Flight (ToF):This technology involves sending a pulse of light at the object and measuring the time it takes for the light to return to the scanner. This time measurement is used to calculate the distance between the scanner and the object.

Now let's take a closer look at some popular handheld 3D scanners and how they stack up against each other.
