Modern 3D scanners are high-tech devices, the main purpose of which is to create three-dimensional models of various kinds of physical objects. Today we will talk with you about optical scanners, which are used in many professional fields and have a lot of unique capabilities. So, let's begin!
Principle of operation
Taken from the site top3dshop.ru
The principle of operation of optical 3D scanners is simple, the scanning process consists in highlighting objects with structured light created by a projector and shooting reflected light from certain angles. The scanned object is illuminated with a light strip or pattern - a reference monochrome pattern. By processing the reflected signal and calculating the location of points on its surface, based on the difference between the projected and reflected images, the computer obtains information for building a 3D model.

All optical scanners are divided into handheld, desktop and floor scanners. Some models are equipped with a color scanning function.
Advantages and disadvantages
Taken from artec3d.com
Many optical 3D scanners allow obtaining data not only on the location of points, but also on their colors, which compares favorably with laser 3D scanners.
Color information can be very important, sometimes color changes can diagnose deviations in the properties of a part of a part. It is also necessary for the subsequent recreation of the appearance of the object, which is critical if it is not about a technical detail, but about a historical object or art object.

Optical tripod scanners are difficult to use for large objects such as vehicles and large parts in mechanical engineering. As a rule, hand-held scanners and tags are used for this purpose. The latter are small black and white sticky notes that are placed on the object surface in order to create anchor points. A large object is scanned piece by piece, and then these separate pieces are stitched together into a solid three-dimensional model.
Another disadvantage of "optics" is that it does a poor job of creating copies of black and shiny objects. However, this problem can be solved in 90% of cases by using a special spray that creates a matte finish.
In terms of price, optical equipment wins, since its acquisition is not associated with such large expenses as when buying laser analogs.
Popular manufacturing companies

Experts from Swansea have been able to adapt the Artec Eva scanner to track marine life and study their lifestyle in their natural environment. By creating special individual tags, scientists were able to gain complete control over the behavior of experimental samples without causing them physical discomfort.
Museums and art
Using the Shining 3D Pro 2X Plus model is able to provide the highest quality digitizing of an object with the most accurate texture rendering. For testing, specialists have chosen multicolored canvases and a vase decorated with intricate ornamentation.
The scanner did an excellent job and clearly proved the fact that it can be safely used for cataloging museum exhibits, as well as issuing souvenirs.

More advanced models (for example, from RangeVision) are used for research work in many universities. So, in one of the universities in Vienna, a unique template was made using a 3D scanner, designed for professional cutting of pig brains. Specialists scanned the material and then shaped it into the desired shape using 3D printing technology.
Medicine
With the Medit i500, dentists can quickly and painlessly scan the dentition of patients with urgent medical needs. With an accurate digital copy of teeth, doctors are able to track the progress of treatment step by step and discuss its effectiveness with other specialists.
3D scanning can also be used to efficiently create prostheses - this solution allows you to obtain significant time and financial savings compared to the costly procedure of creating impressions.
Theatrical art

In order to create colorful scenery at the Bolshoi Theater, it was decided to use the RangeVision Smart model. The craftsmen used a small elephant figurine as a prototype. After the scan was obtained, the theatergoers made a realistic and original foam model out of it, which was subsequently used in performances.
Conclusion
Summing up the above, we can conclude that optical 3D scanners have a huge number of applications. The modern market for such devices is represented by models of various prices - from 30,000 to 1,500,000 rubles.
Hand-held and stationary scanners can be used almost everywhere - in education, fine arts, architecture, medicine, etc. Professional models of 3D scanners have proven their worth in production, reverse engineering and forensics.
