The distance between top and the top of picture and text structure 301 of focusing structure 201 can be 2 microns~150 microns.?
When the distance between focusing structure and picture and text structure very little, it can be understood as picture and text structure is embedded in microlens structure.It focuses
The distance between structure and picture and text structure are smaller, then the thickness that film is imaged is thinner, this not only can be with save the cost, in thermoprint
It is easier to cut off.
It can be seen from the above description that the embodiment of the present application by by picture and text structure setting in the inside of ontology, thus
Realize the purpose for reducing imaging film thickness.Also, it since picture and text structure can be completely covered in ontology, no longer needs to set
Set additional protective layer.In addition, the imaging film in the embodiment of the present application does not have the substrate of satisfactory mechanical property, this make this at
As film may be easy to cut off in thermoprint.
Imaging film thickness in the embodiment of the present application is thin, and thickness can achieve tens microns or less, it might even be possible to reach
It to several microns, and easily is switched off, therefore the imaging film is easy transfer, and can also mitigate weight and save the cost.
In another embodiment, the imaging film further includes catoptric arrangement 401, is set in focusing structure 201 remote
On outer surface from picture and text structure 301, as shown in Figure 7.Catoptric arrangement 401 is used to pass through focusing structure 201 to picture and text structure 301
The light being reflected back carries out secondary reflection again, this allows user to observe its imaging in 301 place side of picture and text structure.
Catoptric arrangement 401 can be transparent material, transparent materials or translucent material.The thickness of catoptric arrangement 401
It can be 0.02 micron~5 microns.Catoptric arrangement 401 can be formed by modes such as magnetron sputtering, vapor deposition, inkjet printings.

Such as first picture and text unit include the first dot matrix in an ON state and the second dot matrix being in an off state, the second picture and text list
Member includes that the second dot matrix in an ON state, then the first picture and text unit and the second picture and text unit have the second common dot matrix.
The position coordinates of the picture and text unit are associated with the position coordinates of the focusing unit, so that all in connection
The dot matrix of state forms at least one suspension image by the focusing unit, i.e., so that the picture and text unit passes through the focusing
Unit forms at least one suspension image.The associated position coordinates that can be picture and text unit are by the position seat of focusing unit
Mark is obtained by default transformation, the default transformation may include coordinate scale transformation or Rotating Transition of Coordinate or they
Combination, but it is not limited to above-mentioned transformation.
For example, can be refering to Fig. 8-Fig. 9.Fig. 8 is the case where focusing unit 22 is in random arrangement, and Fig. 9 is square dot matrix
It is converted according to following preset functions:
ξi=-xoi-arg sinh(yoi),
ηi=yoi-arg sinh(xoi)；
Then, using lattice coordinates as the center of focusing unit 24, the case where obtaining focusing unit aperiodic arrangement.Its
In, ξiAnd ηiFor the transformed position coordinates of focusing unit；xoiAnd yoiFor the position coordinates before focusing unit transformation.Focusing structure
The ratio between region area and the gross area on the ontology surface are known as duty ratio on the surface of ontology.Duty ratio is higher, then
The contrast of the amplification figure arrived is higher.Preferably, the gross area shared by all focusing units is sheet where it in focusing structure
60% or more of the gross area in body surface face.
Please refer to Figure 10 and Figure 11.Figure 10 is that the lattice coordinates of random arrangement in Fig. 8 are acquired after amplification transformation
Picture and text unit arrangement.The amplification transformation are as follows:
αi=0.99xoi
βi=0.99yoi
Wherein, αiAnd βiFor the transformed position coordinates of picture and text unit；xoiAnd yoiIt, can for the position coordinates of focusing unit
With the position coordinates being considered as before the transformation of picture and text unit.Picture and text unit is arranged in the picture and text structure at place without symmetry axis, in random
Arrangement.Figure 11 is in Fig. 9 according to preset function
ξi=-xoi-arg sinh(yoi)
ηi=yoi-arg sinh(xoi)
The lattice coordinates of the focusing unit of arrangement are by rotation transformation counterclockwise (such as 2 ° of rotation, value that but it is not limited to this)
Obtained picture and text unit arrangement afterwards.Wherein, xoiAnd yoiFor the position coordinates of focusing unit.Figure of the picture and text unit at place
It is in aperiodic distribution without symmetry axis in literary structure.
In above-mentioned scaling, rotation transformation, the surface of ontology where focusing structure and picture and text structure may exist one
And only one transformation fixed point is to (surface of ontology selects a point as fixed point i.e. where focusing structure, and is scheming
The point of the corresponding fixed point is selected in literary structure, the two points constitute fixed point to), such as point 21- point 31 (such as Fig. 8 and figure
