Setting 1 includes left first substrate 11, left the second substrate 12, left liquid crystal layer 13 and left distance measurement element (being not shown in Fig. 2).
Left first substrate 11 is parallel with left the second substrate 12 and is oppositely arranged, left first substrate 11 and left the second substrate 12
Material will meet good translucency, good insulating, be easy to form electrode in substrate surface and have the requirement of certain hardness, preferably
For one of polymethyl methacrylate, polyethylene terephthalate, polycarbonate and transparent glass or a variety of.
It is equipped with left first electrode 111 on the inside of left first substrate 11, is equipped with left second electrode on the inside of left the second substrate 12
121, left first electrode 111 and left second electrode 121 are transparency conducting layer, preferably transparent conductive metal oxide skin(coating), wherein
Transparent conductive metal oxide can be used for conductive transparent conductive metal oxide, such as zinc oxide, oxidation to be various
Zinc mixes aluminium, tin indium oxide, tin oxide and tin oxide and mixes one or more of antimony, preferably tin indium oxide (Indium Tin
Oxides,ITO)。
Left liquid crystal layer 13 is arranged between left first electrode 111 and left second electrode 121, on left first electrode 111 and a left side
When applying voltage between second electrode 121, an electric field is formed between left first substrate 11 and left the second substrate 12, electric field makes
Liquid crystal molecule in left liquid crystal layer 13 polarizes and deflects, and changes the arrangement and refractive index of liquid crystal molecule, and refractive index is in center
Symmetrical gradient distribution, to realize the effect of focusing and imaging.
In left lens device 1, left first electrode 111 and left second electrode 121 can there are many arrangement forms, again such as
Shown in Fig. 2, set in the inside of left first substrate 11 there are two left first electrode 111, the two left interval of first electrode 111 settings,
It is equipped with a left second electrode 121 in the inside of left the second substrate 12, left first electrode 111 and left second electrode 121 are asymmetric
Setting.
When applying voltage between left first electrode 111 and left second electrode 121, the power line of electric field is as shown in figure 3, electricity
The line of force can generate non-directional situation in edge, and the liquid crystal molecule state in left liquid crystal layer 13 is as shown in figure 4, left liquid crystal at this time
Liquid crystal molecule in layer 13 is generated torque by electric field, and the main shaft of the liquid crystal molecule in left liquid crystal layer 13 will be parallel with extra electric field
(along the tangential direction of electric field) arrangement, forms particular arrangement and generates specific refractive index and optical characteristics.Due to left liquid crystal layer
The structure of liquid crystal molecule in 13 is anisotropy, has birefringent characteristic, when light passes through left liquid crystal layer 13, polarization of light side
To related with the main shaft of liquid crystal molecule, incident light makes liquid crystal molecule generate polarization in orthogonal light field component.For a left side first
Region between electrode 111 and left second electrode 121, electric-field compulsion change the main shaft direction of liquid crystal molecule, make liquid crystal molecule
Refractive index n is presented in this electric field0；And change the liquid crystal molecule of left liquid crystal layer 13 in the electric field lines of two Electric field edges
Become the main shaft of its script, so forms different refractive index n in two Electric field edges1；But at two Electric field edge centers, liquid
Brilliant molecule is simultaneously not affected by electric field influence, then does not change the main shaft of liquid crystal molecule, refractive index herein is n.As a result, in left lens
The variation of 1 refractive index of device is n0-n1-n-n1-n0, form refractive index gradient.In left first electrode 111 and left second electrode 121

In formula: niFor i-th layer of refractive index, 90 ° of-θiIt is i-th layer of light in i-th layer and the normal for i+1 bed boundary
Angle.
Since liquid crystal molecule is different by electric field strong and weak in left liquid crystal layer 13, refractive index n is formediDifference, but niThe amount of being not easy
It surveys, then can be used mean refractive index approximate with variations in refractive index rate, focal length can then be expressed from the next:
In formula: f indicates focal length,Indicate mean refractive index, α indicates variations in refractive index rate, and D indicates the thickness of left liquid crystal layer 13
Degree.
It, will if changing different electric field strength and direction for the left liquid crystal layer 13 of the left lens device 1 of certain thickness D
Change the refractive index gradient of left lens device 1, i.e. change variations in refractive index rate α and mean refractive indexIt can then be formed different
Shooting angle, thus form different focal lengths.
