What is a 3D scanner?

The world is currently advancing towards the future, along with its cultures and technologies. Man has insatiable necessity for all things. The more he discovers, the more he desires. From the early counting sticks and stones, to the advanced microcomputers, man braces up for what's ahead of him.

One of the advancements in the computer industry is the revolutionary three-dimensional laser scanner, or simply 3D scanner. A 3D scanner is a device that analyzes a real-world object or environment in order to gather digital data from its shape or form, and perhaps its appearance, that is its color. The collated data can be used to construct three dimensional digital models useful for a wide range of purposes.

These modern devices are used widely by the filmmaking industry for production of movies, and the video games industry for developing new games. Other common uses of this technology include industrial design, prosthetics, reverse engineering and material prototyping, product quality control/inspection, and archiving of artifacts and relics.

Different technologies can be used to build these devices for 3D laser scanning services. Each technology comes up with its own advantages, drawbacks and costs. It should be always kept in mind that many limitations in the kind of objects that can be digitized to create electronic representations in three dimensions are still present. For instance, optical technologies come across many difficulties with shiny, highly-reflective or transparent materials.

However, there are unique solutions in 3D laser scanning services for digitizing highly-reflective objects, such as by covering them with a thin layer of white powder that will help more light photons to reflect back to the 3D scanner. Laser scanners can emit trillions of light photons toward a material and only receive a small fraction of those photons back through the optics that they utilize.

The material reflectivity of an object is passed upon the color of the object, or the terrestrial albedo. The basic rule that 3D laser scanning services follow is that a white surface will reflect light photons, while a black surface tends to absorb most of the light particles and reflect only a small amount. Transparent materials such as glass will only refract the light, thus giving a false representation of digital matter three dimensions.
