It is a process that uses a laser machine to shoot a certain wavelength of laser light into the inside of glass or crystal, causing a small burst to form bubbles in specific parts of the inside, thus outlining a pre-determined shape, and also refers to crafts processed with this process in general.
Crystal internal engraving is done by laser as an auxiliary tool. The general 3D imaging technology, which uses the graphic method to obtain 3D images, requires the projection of high brightness laser to measure the object, and the image and model processing of the object by the distance of the laser beam, and the whole process is very complicated. It is time consuming and expensive to take multiple shots of the object to obtain a 3D image of the object. Later, the invention of 3DFlash photography technology greatly solved this problem, making the object into a map is no longer complicated. The image is created in the computer, and then the information is fed into the internal engraving machine to create a beautiful internal engraving craft.
Most of the artifacts you see are not real crystals, but artificial ones. "Laser" is the most useful tool for "internal engraving" of artificial k9 crystal (also called "crystal glass"). Using laser internal engraving technology, flat or three-dimensional patterns are "carved" into the inside of the crystal glass.
Carving is an ancient art, and the general carving process starts from the outside, carving the desired shape from the outside of the material, while the laser can "go deep into the hinterland" like the Monkey King to show off his skills. Look carefully, these glass and crystal products around the entire "carving knife" for the entry and exit of the opening, in this regard, the laser than the Monkey King is even more brilliant, the Monkey to the stomach of others when there is a gap to do it! Laser engraving principle is actually very simple. Laser to be able to carve glass, its energy density must be greater than a certain threshold value of glass destruction, or threshold, and the energy density of the laser at a certain point with its spot size at that point, the same beam of laser, the smaller the spot the greater the energy density generated. In this way, through proper focus, the energy density of the laser can be made to enter the glass and reach the processing area before the threshold of damage to the glass, and in the region where processing is desired exceeds this threshold, the laser produces a pulse in a very short period of time, and its energy is able to heat the crystal to break in an instant, thus producing a very small white spot, carved out the predetermined shape inside the glass, while the rest of the glass or crystal remains intact intact. In fact, this is also known as laser internal engraving assisted imaging technology. With the development of technology, color internal engraving is also expected to be realized
