In addition, this zoom lens preferably also comprises: surround and the lens barrel 204 of fixing described liquid crystal lens, described liquid crystal lens is all perpendicular to the sidewall of described lens barrel 204.
From single chip liquid crystal lens, take the center of liquid crystal lens is starting point, by to being applied to the control of the voltage on liquid crystal lens different radii region, the liquid crystal molecule of controlling in different radii region produces different deflection angles, make the refractive index in liquid crystal lens different radii region different, light produces dispersing or converging in various degree after liquid crystal lens, thereby simulation forms the concavees lens of different focal or the effect of convex lens.By 3, carry out different voltage-controlled liquid crystal lens (having simulated the optical lens with different optical performance for 3) stack combinations, make the first liquid crystal lens 201 there is optical zoom function, the second liquid crystal lens 202 has optical imagery function, the 3rd liquid crystal lens 203 has the function of imaging being corrected to eliminate distortion, aberration etc., thereby has formed the zoom lens of a telotism.
It should be noted that, in actual applications, it is so simple that the optical lens that liquid crystal lens is simulated never stops concavees lens or convex lens, by the voltage in liquid crystal lens zones of different, control more accurately aspheric mirror that liquid crystal lens is further can simulated optical structural and optical properties more complicated etc.
And, in the zoom lens of the present embodiment, each liquid crystal lens is not limited to simple function, also can possess other function, as the first liquid crystal lens 201 not only has the function of zoom, can also realize the function of optical imagery and rectification, the second liquid crystal lens 202 is except having optical imagery effect, also can correct distortion and aberration, and play certain zoom effect, the 3rd liquid crystal lens 203 has the function of rectification, zoom and imaging, and the ratio of the function that just each liquid crystal lens has can be different.
At least 1 in the zoom lens that the present embodiment provides in all described first substrates and second substrate is preferably gradually changed refractive index formula substrate.This gradually changed refractive index formula substrate is the substrate of liquid crystal lens, there is again the optical property identical with optical lens, and be slab construction, the optical lens that Thickness Ratio has identical optical performance is thin, zoom lens for the present embodiment can be in attenuate camera lens thickness, the performance that strengthens camera lens, makes camera lens imaging quality higher.More preferred, described first substrate and described second substrate described in adjacent two layers between liquid crystal layer are gradually changed refractive index formula substrate.In actual production, the number needs of the gradually changed refractive index formula substrate using in zoom lens will consider according to the needs of actual optical property and cost factor.In addition, described gradually changed refractive index formula substrate preferably can be gradually changed refractive index formula glass substrate.
For the zoom lens that the present embodiment provides all can well be worked in various temperature environment, described zoom lens preferably also comprises temperature inductor.By adding these for the device of temperature compensation, monitoring temperature, make zoom lens can in the environment such as low temperature, keep good serviceability.
