The handicraft that sees normally is not true crystal mostly, however man-made is crystal. "Laser " it is crystal to man-made (also say " crystal " ) undertake " inside vulture " the most useful tool. Use technology of the carve inside laser, will planar or stereo design " carve " the interior in crystal.

Vulture block-printed edition is an ancient art, general sculpture craft is from outside quarter, from material exterior carve gives the appearance of a hope, and laser can resemble Sun Wu however sky is same " thorough hinterland " go hands or feet of put to good use. Young analyse looks, did not offer right-down all round these glass, crystal goods " burin " the mouth of pass in and out, with respect to this character, laser is even more brillant than Sun Wu sky, grandson there also should be aperture to just go when the monkey is gotten in past family abdomen! Laser carves a principle actually very simple also. Laser wants to be able to carve glass, its energy density must be more than the some that makes glass is destroyed critical value, or weigh threshold value, and the energy density of laser someplace and its size in this bits of facula is concerned, same bundle of laser, the energy density that the place with less facula produces is bigger. Such, pass proper focusing, can make the energy density of laser is in enter glass to reach before reaching treatment area under glass destroy threshold value, and the area that machines in the hope exceeds this one critical value, laser produces pulse inside cutty time, its energy can make in the instant burst of crystal be heated, produce dinky white spot thereby, in vitreous interior vulture gives booked appearance, and glass or crystal others maintain unvarnished and in good condition nondestructive.

The carve inside laser is assisted like the technology

Actually, general 3D is become like the technology, use graphics method to get 3D picture, need projects tall bright laser will measure an object, through stimulating the far and near of beam of light, undertake the image of the object and model are handled, whole process is very multifarious. Want to film for many times, ability acquires the 3D image of the object, price is high, and rate is very slow, especially unwell at taking the picture of mobile object. Whole process is as long as a few minutes sometimes, during filming, the object is not kinetic. This means technology of this kind of photography to be able to be applied only go up in scenery and immobile object.

Successors invented 3DFlash! Photography technology, this technology is filming human body respect has absolutely advantage -- can get high resolution inside 0.01 seconds, obtain the three-dimensional data with person accurate face. 3DFlash! Three-dimensional flashlight can be mixed common join of camera of 2 dimension word, code tailor-made grating umbriferous to object surface, and shoot this encode picture by digital camera. Pass special decipher software, undertake an analysis to encode image, find out the 3D information of axis of the X of image, Y, Z, below this measure, the figure that processing gives is the 3D net figure that reseau comprises, stick the skin and chromatically to person face namely next. After finishing, a 360 degrees 3D whole head is made in computer so. Computer inputs information again inside vulture machine, can make handicraft of the carve inside perfect image.
