(2) with the method design holographic light path of laser hologram or calculation holographic, on recording layer, be produced on 5V～50V AC field and make the erasable holographic lens of time spent lens effect;
(3) the different holographic recording optical path of design is made electric control focusing holographic lens and hologram diffraction lens with different focal;
(4) with lens stack, combination, the integrated electric control zooming and optical imaging system that becomes of one group of different focal;
(5) computer program calculates and controls the electric field of single lens, and regulation and control combination and order are realized the continuous vari-focus or the discrete zoom function of electric control zooming and optical imaging system.
Holographic lens is made and can be made positive lens with assembling spherical wave and plane wave optical interference circuit, in liquid crystal cell, the positive first-order diffraction efficient of holographic lens is improved holographic information recording.
The present invention is based on and makes the H-PDLC lens with electric control focusing function, and automatically controlled optical imaging system is formed in the automatically controlled lens stack of the H-PDLC of N different focal, calculates by program, regulates automatically controlled combination order and obtains 2
NIndividual focus, the realization system function of focusing continuously.
The present invention adopts and makes the automatically controlled lens of novel PDLC is the element of optical system, combines the optical function and the automatically controlled characteristic of optical lens, the quantity of the optical element in the saving system greatly.Simultaneity factor adopts computer control automatic focusing, has movement-less part, and the response time is short, and focusing accurately is easy to fine qualities such as integrated.Automatically controlled optical focal distance setting system is at zoom information sign indicating number reading system, optical memory, and the first-class aspect of the optics of DVD player is with a wide range of applications.

Embodiment
The present invention is further illustrated below in conjunction with embodiment and accompanying drawing.
Implementation step of the present invention is:
1, preparation liquid crystal grating element: it comprises two glass substrates that are coated with conductive layer, the recording layer that the PDLC material that irritating in glass substrate has 5～10 μ constitutes;
2, design holographic light path with laser hologram technique, make holographic lens on recording layer, these lens are under the effect of 5～50V AC field, and lens effect can be wiped;
3, the different holographic light path of design uses the same method and makes the hologram diffraction lens with different focal;
4, with lens stack, combination, the integrated electric control zooming and optical imaging system that becomes of one group of different focal;
5, computer program calculates and controls the electric field of single lens, reaches continuous vari-focus or discrete zoom purpose.
By Fig. 1 to shown in Figure 4, its explanation holographic production PDLC lens, each single element lens is at electric field action and do not have to have under the electric field action and focus on and out-focus two specific characters, i.e. " 0 " of focus and " 1 " switching characteristic; The lens stack of two different focal can obtain four diverse location focuses, can obtain 2 on N lens superposition theory like this
NIndividual focus is calculated the continuous vari-focus function that regulation and control can obtain optical imaging system by computer program.
Polymer dispersion liquid crystal material (PDLC) is to be scattered among the solid polymer polymer matrix and the novel optical material that forms has significant electric-controlled switch characteristic by liquid crystal droplet.Prepare two glass substrates that nesa coating is arranged, the recording layer that coating one deck is made of the potpourri (polymer dispersion liquid crystal material) of the Photosetting macromolecule pre-polymerization material of 5～10 μ m and liquid crystal between glass substrate, method design holographic light path with laser hologram or calculation holographic, as making positive lens with assembling spherical wave and plane wave optical interference circuit, with holographic information recording in liquid crystal cell, make holographic lens, the positive first-order diffraction efficient of lens is improved.
Because the effective refractive index of liquid crystal droplet is subjected to the electric field regulation and control, under certain alternating current effect, the holographic lens focussing force disappears, and can form the lens of " 0 " and " 1 " formula switch zoom.Design different holographic recording optical paths and make the electric control focusing holographic lens with different focal, these single automatically controlled lens have the focusing and the out-of-focus state of " 0 " and " 1 " according to effect of electric field; The thickness of monolithic zoom lens should approach as far as possible, is beneficial to integrated.With N the automatically controlled lens stack of PDLC that the focal length parameter is different, regulate the order of electric field regulation and control, system can obtain 2
NIndividual focus; Calculate and the electric field regulation and control combination of control monolithic PDLC lens and order can be realized optical system continuous vari-focus function with computer.
