As shown in Fig. 4 a-b and the 5a-b, tunable optical component 300 can comprise for example various liquid crystal materials.Fig. 4 illustrates the material 91 without any scattered light under the voltage condition.In other words, when supply with zero voltage signal on being present in substrate 190 and 191 transparency electrode 90 and 92 the time, incident light 5 be scattered (Fig. 4 a), and, when supplying with sufficiently high voltage, material 91 becomes transparent (Fig. 4 b) so that produce (basically) unscattered light.Fig. 5 a-b shows another kind of material, and this material is that transparent (Fig. 5 a) when not applying voltage.When the transparency electrode 93 on being present in substrate 193 and 195 and the voltage at 95 two ends are zero, material 94 be transparent (Fig. 5 a), and when applying sufficiently high voltage at the electrode two ends, incident light 5 becomes (Fig. 5 b) of scattering.
As shown in fig. 6, tunable optical component 300 can comprise for example liquid crystal material.From the top to the bottom, have glass substrate 100, transparency electrode 101, oriented layer 102, liquid crystal material 103, isotropic layer 104, transparency electrode 105 and glass substrate 106.By supplying with zero voltage signal or non-zero voltage signal, because the true incident light 5 that applies the orientation that changes liquid crystal molecule of electric field is refracted or is not refracted, and refraction ground can not take place and passes through in light beam.
Influence two polarization directions if desired, two such elements need be used for following configuration so: wherein the orientation of the liquid crystal molecule in element is vertical mutually.It is identical that the orientation of molecule can keep, but need insert half-wave plate under such situation between element.
Tunable optical component 300 for example can comprise as at so-called chirality (chiral) liquid crystal material shown in Fig. 7 a-b.At zero-voltage state, liquid crystal 112 reflection circle polarization light belt 25a, and the circular polarization light belt 25b of reversed electric field (Fig. 7 a) by transmission.Removed the helicoidal structure of liquid crystal 112 at the voltage at transparency electrode 111 that is placed on glass substrate 110 and 114 tops and 113 two ends, and made this cell transparent (Fig. 7 b).The configuration of two unit can be used for reflecting two polarization directions.In this configuration, a kind of possibility is to use the unit that comprises chiral material, the left side of this chiral material reflection circle polarised light and the right avertence direction of shaking.The identical chiral material that has the unit of half-wave plate between another possibility is to use and is included in.

Tunable optical component 300 can be as at liquid-crystal refractive-index gradient (GRIN) lens or the array shown in Fig. 9 a-b.Such element comprises patterned electrodes.If two surfaces of this unit all comprise patterned electrodes, these surfaces mutually alignment so that almost completely overlapping of these pattern displaying.In this case, the electromotive force between electrode is the highest.Outside electrode, the magnetic line of force leaks into the outside of unit and causes the magnetic line of force heterogeneous.As a result, in the zone that does not comprise electrode, form refractive index gradient.(also a), then form spherical lens, and on periodic distance, use lineation electrode can cause producing cylindrical lens if transparency electrode comprises circular hole referring to Figure 10.The geometry of electrode also can adopt other forms, and other forms of example has been shown in Figure 10 b-d.Fig. 9 illustrates the unit with the patterned electrodes (131,136) on glass substrate (130,137) that comprises liquid crystal (133).The oriented layer of being made by the friction polymer layer (132,135) causes the macroscopic orientation of liquid crystal molecule.Patterned electrodes can have any structure, at various examples shown in Figure 10 a-d.When the voltage that is applied to electrode (131,136) two ends is zero, liquid crystal molecule is orientated coaxially and is not had a lensing in the unit, and as shown in the figure on Fig. 9 top (top drawing), wherein wave beam 5 is through these unit and be not changed.Shown in the figure of Fig. 9 bottom, apply electric field at these two ends, unit and cause the refractive index gradient that causes in the zone between electrode, and the path of light beam 5 is changed
In another embodiment, grin lens can result from and provide electrode pattern and another surface does not comprise the unit of any pattern on a surface in the surface only.In yet another embodiment, (some) patterned electrodes are covered by the layer of the very high sheet resistance of (in the MegaOhm/square range) with megohm/square range.
Above-mentioned grin lens also shows polarization correlated.Influence two polarization directions if desired, two such elements need be used for configuration, and the orientation of the liquid crystal molecule in this configuration in the element is mutually perpendicular.The differently-oriented directivity of molecule can keep identical in two elements, still, under the sort of situation, need insert half-wave plate between element.
In this application, importantly have low by reflection with absorb the loss that causes.Above-mentioned GRIN notion can minimize these losses so that can obtain higher transmissivity (transmission).
Can obtain isotropic scattering properties with several different methods.Preferably, selection comprises the optical element 300 of the liquid crystal cells that comprises liquid crystal material, and this liquid crystal material is selected from the group that comprises LC gel (gel with liquid crystal structure), chirality gel and PDLC (PDLC) material (also seeing below) with negative dielectric anisotropic.
