Human eye is when observing an object, because two horizontally separated two different positions, sees the angle difference of object, and viewed subject image is different, exists an aberration between them.Because the existence of this aberration, we can experience three-dimensional variation of the degree of depth of a three-dimensional world by brain, the principle of stereoscopic vision of Here it is human eye.
Around this principle, our people is for producing a kind of material---grating, and the incident light that makes two 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 cause illusion, experience three-dimensional stereopsis with degree of depth.
Often for obtain better stereoeffect I not merely with two width of cloth image makings, but go to constitute with the stereo-picture of one group of sequence, under these circumstances, position difference according to the observation, as long as see two sub-pictures in this sequence simultaneously, can experience three-dimensional stereo effect.
Grating is flat between two, notice that two strain line angles to grating want keeping parallelism, thereby two soon to be same image, if image is made of a row continuous animation, so when eyes move up and down or grating are stirred up and down, the angle of eyes and grating will change, and we also will see consecutive image one by one, promptly see the effect of an animation or change picture.
Grating is actual to be one deck lens, comprises a thin slice or transparent panel, and its one side is made up of strip lens, and another side is the plane.Grating is positioned over the front of image,, will sees the image of back through the endways lens of a rule when we see over from the front of grating.Image is not normal plane pattern, but and the identical bar graph of the width of fringe on the grating.Bar graph is not a pattern, but the stack of a plurality of patterns.We are printed on the back side of grating thin slice with the image of this stack, perhaps print to and are bonded at the original screen panel back side on the paper, leave certain distance and watch, and just can see a lifelike stereo-picture.
Grating mainly contains slit grating and column mirror grating two classes.Slit grating is that the line style grating is comparatively ripe the earliest grating, and its image-forming principle is 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, is the grating of present main flow.
