-part in this cycle is filled with black picture element, the black picture element of such as 50%, as in fig. ib
-creating periodically image, this periodicity image has the resolution identical with the described cycle, and has and wanted
The size that the parallax barrier asked is identical, and repeat to fill according to the described cycle,
-use transparent or semitransparent substrate and suitably playback system to form described periodicity image, enabling
Zone of opacity is obtained for each black picture element in described periodicity image.
Therefore, in a variant, before parallax barrier is formed, it is also possible to the described cycle showing as parallax barrier
Property image apply discrete filter, to be distributed displacement on this parallax barrier and this both discrete picture.
This association is to gather discrete picture ID and optical selector SO, to obtain iridescent image II.Work as optical selector
When SO is made up of lens (linear or spherical), discrete picture ID must be placed at the focal length of described lens substantially.Generally, business
The thickness of the network of lenses set up in industry meets this requirement, so that this image must be placed in the face relative with described lens
Upper (referring to Fig. 5 and Fig. 6).
When optical selector SO is parallax barrier, a distance is preferably set between this fence and this ID.In order to obtain
Rainbow effect, i.e. so that the eyes perception different images of observer, it is preferably ensured that this distance is the least.
