Description
Technical Field
The invention relates to a compound eye system, in particular to a non-uniform zooming curved surface compound eye array based on dielectric elasticity driving, and belongs to the field of optical compound eye zooming imaging.
Background
Two eyes exist in nature, one is a single-limbed eye of a mammal, and the other is a compound eye of an insect. The compound eye is composed of a plurality of small eyes with the same structure, and the small eyes are distributed on the curved surface. Compared with a single-aperture eye, the compound eye has the advantages of large field of view, high sensitivity, compact structure and the like. The parallel compound eye is a form of compound eye, each optical channel of the compound eye separately images a target without mutual interference, and the compound eye has the advantages of simple structure, small volume, large imaging field of view and the like. The optical system with the zooming function can realize clear imaging of targets at different distances. The traditional parallel compound eye adopts a micro-lens array processed by glass or resin materials as an optical system, however once the micro-lens array is processed, optical parameters such as focal length and the like of the micro-lens array are fixed, and the micro-lens array is difficult to have a zooming function, so that targets with different distances cannot be imaged clearly. Although zoom lenses such as elastic film lenses, liquid crystal lenses, electrowetting lenses, etc. are available at present, these zoom modes have disadvantages related to gravity, vibration, temperature sensitivity, polarization, etc. Therefore, it is necessary to provide a new type of variable focal length curved compound eye array.
Disclosure of Invention
In order to solve the problem that the zooming of a curved-surface fly-eye array is difficult to satisfy in the prior art, the invention mainly aims to provide a non-uniform zooming curved-surface fly-eye array based on dielectric elastic driving. The dielectric elastomer has the characteristics of simple structure, high response speed, large deformation and the like, so that the zooming parallel type curved compound eye array has the advantages of large zooming range, small processing difficulty, simple structure, high zooming efficiency and the like.
The purpose of the invention is realized by the following technical scheme.
The invention discloses a non-uniform zooming curved compound eye array based on dielectric elasticity driving, which is used for realizing high-resolution imaging of human-simulated eyes and comprises an upper curved metal plate, a lower curved metal plate, a dielectric elastomer, small holes, a switch and a high-voltage power supply. The upper curved surface metal plate and the lower curved surface metal plate are uniformly distributed with a plurality of small holes, the number and the caliber of the small holes of different rings are different, the small holes of the same ring have the same caliber, and the small holes are non-uniformly distributed at the positions of the upper curved surface metal plate and the lower curved surface metal plate. The dielectric elastomer is positioned between the upper curved metal plate and the lower curved metal plate, the upper surface of the dielectric elastomer is contacted with the lower surface of the upper curved metal plate, and the lower surface of the dielectric elastomer is contacted with the upper surface of the lower curved metal plate. One end of the switch is connected with the upper curved surface metal plate, the other end of the switch is connected with the high-voltage power supply, and the other end of the high-voltage power supply is connected with the lower curved surface metal plate. When the switch is in an off state, the shape of the dielectric elastomer is a plane, and the focal length of the nonuniform zooming curved compound eye array is infinite. When the switch is in a closed state, the upper curved surface metal plate and the lower curved surface metal plate are connected with a high-voltage power supply, opposite charges of the upper curved surface metal plate and the lower curved surface metal plate are mutually attracted, and Maxwell stress is generated in the dielectric elastomer, so that the thickness of the dielectric elastomer is reduced. Because the volume of the dielectric elastomer is unchanged, the dielectric elastomer is convexly deformed at the small holes and has a lens-like profile, so that the micro-lens array is formed. Because the small holes have different calibers, the micro lenses formed by the small holes of different rings have different focal lengths under the same driving voltage. The magnitude of the Maxwell stress of the dielectric elastomer is a function of the magnitude of the applied voltage, and a large voltage magnitude will cause a large deformation, so that the focal length of the non-uniform variable-focus curved compound eye array is changed by adjusting the magnitude of the voltage applied to the dielectric elastomer. When the voltage applied to the dielectric elastomer is removed, the dielectric elastomer is quickly recovered to the initial state, and the focal length of the nonuniform varifocal curved compound eye array is infinite.
The invention discloses a working method of a nonuniform zoom curved compound eye array based on dielectric elasticity driving, which comprises the following steps:
in the initial state, the dielectric elastomer has uniform thickness and infinite focal length. The direct current is output by controlling the direct current power supply, the positive electrode and the negative electrode are respectively connected to the upper metal plate and the lower metal plate, a voltage difference is generated between the two metal plates, Maxwell stress is generated in the dielectric elastomer, the dielectric elastomer is softened, the thickness of the dielectric elastomer is reduced, the dielectric elastomer at the edge part of each round hole is extruded into the round hole, the curvature radius of the inner film of each round hole is changed, and therefore the focal length of the non-uniform zooming curved compound eye array is changed. When the power supply is turned off, Maxwell stress generated in the dielectric elastomer disappears, the dielectric elastomer in each round hole restores to the initial state, and the focal distance becomes infinite.
Has the advantages that:
1. according to the non-uniform zooming curved surface fly-eye array based on the dielectric elastic drive, the dielectric elastic body is used as the drive, the dielectric elastic body is located between the two curved surface metal plates, the two curved surface metal plates are provided with small holes with different calibers, the dielectric elastic body is deformed by applying voltage to the two curved surface metal plates, a micro-lens array structure is formed, the non-uniform curved surface fly-eye array is achieved, and the non-uniform zooming curved surface fly-eye array has the advantages of being large in view field, simple in structure, non-uniform in focal length and the like.

Detailed Description
The following describes embodiments of the present invention with reference to the drawings.
As shown in fig. 1, the nonuniform zoom curved compound eye array based on dielectric elastic drive disclosed in this embodiment includes an upper curved metal plate 1, a lower curved metal plate 2, a dielectric elastic body 3, an aperture 4, a switch 5, and a high voltage power supply 6. The upper curved surface metal plate 1 and the lower curved surface metal plate 2 are uniformly distributed with a plurality of small holes 4, the number and the caliber of the small holes 4 of different rings are different, the small holes 4 of the same ring have the same caliber, and the small holes 4 are non-uniformly distributed at the positions of the upper curved surface metal plate 1 and the lower curved surface metal plate 2. The dielectric elastomer 3 is positioned between the upper curved metal plate 1 and the lower curved metal plate 2, the upper surface of the dielectric elastomer 3 is contacted with the lower surface of the upper curved metal plate 1, and the lower surface of the dielectric elastomer 3 is contacted with the upper surface of the lower curved metal plate 2. One end of the switch 4 is connected with the upper curved surface metal plate 1, the other end is connected with the high-voltage power supply 6, and the other end of the high-voltage power supply is connected with the lower curved surface metal plate 2. As shown in fig. 1(a), when the switch 5 is in the off state, the shape of the dielectric elastomer is a plane, and the focal length of the non-uniform zoom curved compound eye array is infinite. As shown in fig. 1(b), when the switch 5 is in the closed state, the upper curved metal plate 1 and the lower curved metal plate 2 are connected to a high voltage power supply, the opposite charges of the upper curved metal plate 1 and the lower curved metal plate 2 attract each other, and Maxwell stress is generated inside the dielectric elastomer 3, resulting in a reduction in the thickness of the dielectric elastomer 3. Since the volume of the dielectric elastomer 3 is constant, the dielectric elastomer 3 will be deformed convexly at the aperture 4, having a lens-like profile, forming a microlens array 7. Since the apertures 4 have different apertures, the microlenses formed by the apertures 4 of different rings have different focal lengths under the same driving voltage. The magnitude of Maxwell stress of the dielectric elastomer 3 is a function of the magnitude of the applied voltage, and a large voltage magnitude will cause a large deformation, so that the focal length of the non-uniform variable focal length curved compound eye array can be changed by adjusting the magnitude of the voltage applied to the dielectric elastomer 3. Once the voltage applied to the dielectric elastic body 3 is removed, the dielectric elastic body 3 is rapidly restored to the original state, and the focal length of the non-uniform variable-focus curved compound eye array is infinite.
As shown in fig. 2 and 3, the dielectric elastomer 3 is located between the upper curved metal plate 1 and the lower curved metal plate 2, a plurality of rings of small holes 4 are distributed on the upper curved metal plate 1 and the lower curved metal plate 2, the number and the caliber of the small holes 4 of different rings are different, and the small holes 4 of the same ring have the same caliber.
When the switch 5 is in an off state, as shown in fig. 4, the dielectric elastomer 3 is located between the upper curved metal plate 1 and the lower curved metal plate 2, the upper surface of the dielectric elastomer 3 is in contact with the lower surface of the upper curved metal plate 1, and the lower surface of the dielectric elastomer 3 is in contact with the upper surface of the lower curved metal plate 2. The shape of the dielectric elastomer is a plane, and the focal length of the nonuniform zooming curved compound eye array is infinite.
When the switch 5 is in the closed state, as shown in fig. 5 and 6, Maxwell stress is generated inside the dielectric elastomer 3, which causes the dielectric elastomer 3 to deform at the small hole 4, having a lens-like profile, forming the microlens array 7.
In summary, the non-uniform variable focal length curved fly-eye array driven by the dielectric elastomer 3 adopts the dielectric elastomer 3 as a drive, the dielectric elastomer 3 is located between the upper curved metal plate 1 and the lower curved metal plate 2, the dielectric elastomer 3 is deformed to form the microlens array 7 by applying voltages to the two curved metal plates, and the focal length of the microlens array 7 can be changed by applying drive voltages with different amplitudes. Compared with the drive of other zoom lenses (such as elastic film lenses, liquid crystal lenses and electrowetting lenses), the lens has the advantages of insensitivity to gravity, vibration and temperature, independence on deflection and the like.
