How Do Handheld Scanners Work

Are you looking to buy a handheld 3D scanner?

3D scanning is one of the most innovative technologies that has given us amazing tools for invention and industry. Because of 3D scanners and the ability to scan moving parts and soft materials, we’ve seen advanced robotic technology, medical discoveries, and amazing jewelry.

To ignore the power of 3D scanning would be foolhardy, and once you know how to use one, it can make your life – or your business – much easier. That said, you need to know how 3D scanners work to use them most effectively.

Let’s look at the basics of handheld scanners and how they work. 

What are Handheld Scanners?

Handheld 3D scanners are devices that are used to capture the physical dimensions of an object in three-dimensional (3D) space.

The data captured by the scanner is then transferred to a computer where it can be processed and manipulated using various software programs.

How are the 3D Scans Captured?

Now that we’ve covered what handheld scanners are and how they basically work, next up are the ways they can capture or scan objects. There are two ways that a handheld scanner can scan an object. This is either through linear scanning or matrix scanning. 

Both linear and matrix scanners are designed to work quickly and efficiently. The scanning process usually only takes a few seconds, and the data is immediately available to be read by a computer. 

Linear Scanners

Linear scanners work by moving a laser beam across a row of items to be scanned, one at a time. As each item is scanned, the line of laser light is reflected back into the scanner. The scanner decodes the pattern of light and dark areas into digital data that can be read by a computer.

Matrix Scanners

Matrix scanners work by scanning a grid of small areas, one at a time. The scanning process is similar to that of a linear scanner, but the grid pattern allows the scanner to capture a more complete image of the item being scanned.

How Long Does the 3D Scan take?

The scanning process can take anywhere from a few seconds to a few minutes, depending on the size and complexity of the object being scanned. After the scanning is complete, the 3D image can be viewed on a computer or other device. 

How Are the 3D Scans Processed?

Once the scanner captures the 3D Scan data, it is then transferred to a computer where it can be processed and manipulated.

The software that is used to process and manipulate the data is known as CAD (Computer Aided Design) software. This type of software is used by engineers and architects to create models and drawings of objects.

What Can I Do With the 3D Scan Data?

The 3D models can be used for a variety of purposes, such as creating prototypes, analyzing products, reverse engineering, or even dentistry. An example is the Aoralscan 3 Intraoral Scanner used to scan dental structures.

Some of the most common uses for 3D models are for creating accurate representations of objects for engineering or manufacturing purposes. 

The Future of Scanning is Now

Handheld scanners and their technology are now being used more widely in different areas right now. It helps make life easier and gives more depth to different work functions. So go get one yourself now!
