Description
Technical field
The utility model relates to a kind of grating, more specifically to a kind of grating sheet.
Background technology
Stereotome can present three-dimensional scenery true to nature, is the another much progress of scene record after black-and-white photography and colour phhotograpy.Its principle is to utilize grating sheet, and the incident light that makes two of beholders is by refraction and diffraction take place behind the grating, and right and left eyes is seen the image of two width of cloth or several different angles respectively, and then causes illusion, experiences the three-dimensional stereopsis with degree of depth.
Grating on the above-mentioned grating sheet is actual to be one deck lens, is a thin slice or a transparent panel of being made up of strip lens, and the back side is flat.The starting material of grating sheet adopt PET, PP, PVC, PMMA usually.When we see over from the front of grating, watch the image that is positioned at the lens back with regard to being equivalent to see through the endways lens of a rule.And these images are not normal plane patterns, but and the bar graph that coincide of the width of fringe on the grating, and these bar graphs are not patterns, but the stack of a plurality of patterns.We are printed on the back side of thin slice or transparent panel with these bar graphs, perhaps print to be bonded at the thin slice or the transparent panel back side on the paper then, leave suitable distance and watch, and just can see a lifelike stereo-picture.
The pitch of above-mentioned grating sheet is the width of grating grid line, and the line number is meant the number of the pitch that is comprised in the per inch.Relational expression is: line number=per inch/pitch.50 line gratings just are meant and comprise 50 lens pillars (0.5 of positive and negative deviation) in one inch.
The grating that adopts mainly contains slit grating and column mirror grating two classes at present.Slit grating is that the line style grating is comparatively ripe the earliest grating, and its image-forming principle is the principle of pin-hole imaging.But therefore the very low only 20-30% of slit grating transmittance needs illuminating lamp, and neither environmental protection is not energy-conservation yet.The image-forming principle of column mirror grating is a lens refraction catoptric imaging, be the grating of present main flow, but the grating sheet of existing employing column mirror grating adopts post forming usually, and its shortcoming is that focusing is poor, sharpness is low, manufacturing cost is high.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the defective that the prior art focusing is poor, sharpness is low, manufacturing cost is high, a kind of grating sheet is provided, and this grating sheet sharpness height, focusing be strong, be suitable for making various stereotomes, low cost of manufacture.
The technical scheme that its technical matters that solves the utility model adopts is:
A kind of grating sheet, comprise transparent base, the upper surface of transparent base is placed with a plurality of lens pillars, and each lens pillar is parallel to each other and is evenly distributed successively, the lower surface of transparent base is the plane, it is characterized in that: the xsect top of described each lens pillar all has one section arc curve; Along with the vertical vertical direction of lens pillar, the transparent base of per inch is distributed with 49.5-50.5 bar lens pillar.Because the retractility of transparent base (adopting plastics usually), can't accurately accomplish just have 50 lens pillars on one inch the transparent base, allow certain error, allow the transparent base of each inch to have generally speaking ± error of 0.5 lens pillar, promptly in fact, the transparent base of each inch has 50 ± 0.5 lens pillars, and the width (grating pitch) that can determine every lens pillar thus is 25.4mm/ (50 ± 0.5), i.e. 0.5030～0.5131mm.
The line number of grating sheet is set to 50 lines (transparent base that is per inch is distributed with 50 lens pillars), 50 line grating sheet material pitch are about 0.5mm, therefore grating sheet is viewed and admired usually apart from being 0.25～2.5 meter after making stereogram, therefore is highly suitable for all kinds of tridimensional advertisement lamp box classes, large stereo billboard etc.The print request original design pattern of 50 line grating sheet materials will reach more than the 250dpi, and it is very big that the 3 D grating after the printing is drawn clear stereoscopic depth.And because the precision of current printer is more and more higher, the printable grating pattern that goes out 50 lines of present Epson high precision printer, therefore 50 line gratings are well suited for solopreneur's use, only need computer, the large format high precision printer that Three-dimensional Design Software is installed can offer a tame solid and design and produce the chamber.The xsect of the lens pillar of above-mentioned grating sheet has one section arc curve, and adopt three-dimensional roller to produce, have that transparency height, sharpness height, focusing are strong, forming, stable material quality are not yielding, environmental protection, be easier to carry out characteristics such as post-production in conjunction with extrusion equipment.
A kind of more excellent scheme, described arc curve are one section circular arc.Arc curve is set to circular arc, is convenient to be provided with the parameters of grating sheet, and processing and fabricating is easy.
Preferred scheme, the radius of described circular arc is 0.145～0.625mm.On the grating sheet of per inch, when the bar number of lens pillar was determined, the width of lens pillar had just been decided.And under the situation that the lens pillar width is determined, the radius of circular arc is big more, circular arc is just smooth more, then the focusing distance of lens pillar is just big more, width and arc radius according to lens pillar, just can calculate the focusing distance of lens pillar, determine that thus the thickness range of transparent base (being grating sheet) is between 0.35～1.5mm, simple and convenient.The radius of circular arc is set to 0.2515～1.0mm, has both taken into account the thickness of grating sheet, can guarantee that again the stereogram of making has the stereoscopic sensation of certain depth, guarantees good stereoeffect.
Described transparent base can be PET, PP, PVC, PMMA.
Grating sheet of the present utility model, the line number of grating sheet is set to 50 lines, and grating sheet is viewed and admired usually apart from being 0.25～2.5 meter after making stereogram, therefore is highly suitable for all kinds of tridimensional advertisement lamp box classes, large stereo billboard etc.; And the xsect of the lens pillar of grating sheet has one section arc curve, and adopts three-dimensional roller to produce in conjunction with extrusion equipment, therefore has the transparency height, the sharpness height, focusing is strong, forming, and stable material quality is not yielding, environmental protection and be easier to carry out characteristics such as post-production.
