What is grating

Optics by a large number of equal width equally spaced parallel slits is referred to as grating (grating). Gratings are commonly used to carve on a large number of parallel glass made the score, the score for the non-transmitting portions, the score between the two smooth portions can light, the equivalent of a slit. Raster refined within 1cm width engraved with thousands of thousands of pieces and even the score. This use of transmission diffraction grating is called a transmission grating, as well as the use of the score between the two reflected light diffraction grating, such as a plurality of parallel notches carved on the metallized surface of the layer, the score between the two smooth metal surface can reflect light, which is called the grating reflection grating.

Grating is a combination of digital technology and traditional printing technology, we can show different special effects in a special film. On the plane show lifelike three-dimensional world, the film-like smooth animation clips, Magic incredible effect. The grating is a thin strip of lenses, when we look at the past from the lens side, you will see the other side of the image on a sheet on a very fine line, and the position of this line by the angle of observation decision. If we bring the number of images on different lines, corresponds to the width of each lens, respectively, are arranged in the order printed on the back of the branches grating sheet, when we observe from different angles through the lens, you will see a different image.
