[0001] 本发明涉及的是一种光动力钻,具体地说是一种基于多芯光纤的自组装式光动力钻。 [0001] The present invention relates to an optical power drill, in particular based on self-assembled multi-core fiber optical power drill.

背景技术 Background technique

[0002] 光致旋转是实现微机械马达的有效手段,随着科技的发展,以及工艺加工技术和计算机技术的发展,光致旋转的应用前景将日益广泛,光致旋转的方法不仅可以应用到微全分析系统中充当搅拌器,还可以应用到微泵中,也可以用来研究旋转马达蛋白、流体的微观性质、细胞膜剪切力、微钻等,因此,该技术的深入研究为微生命科学和生物医学提供了一种强有力的工具。 [0002] The photocurable micromechanical rotation motor is an effective means to achieve, with the development of science and technology and the development of processing technology and computer technology, the light-induced rotation prospect will become increasingly widespread, photoreduction methods can be applied to not only rotate micro total analysis system acts as a stirrer may also be applied to a micro pump, a rotary motor may be used to study protein, microscopic properties, the shearing force of the fluid cell membranes, micro-drilling, therefore, further study of this technique is the micro-life and biomedical science provides a powerful tool.

[0003] 1936年,RA Beth在实验上让一束圆偏振光通过细丝悬挂的半波片,首次利用光束中光子的角动量实现了物体的旋转(Beth R A. Mechanical detection and measurement of the angualarmomentum of light. Phys. Rev. , 1936, 50 :115_125)。 [0003] 1936, RA Beth experimentally so that the half wave plate circularly polarized light bundle of filaments of the suspension, the first use of the photon beam rotation angular momentum to achieve the object (Beth R A. Mechanical detection and measurement of the .. angualarmomentum of light Phys Rev., 1936, 50: 115_125). 自此以来人们一直在不停的探索着实现光致旋转的方法。 Since then people have been constantly exploring methods to achieve light-induced rotation. 自从1986年Askin等人提出了“光镊”实现了对粒子的三维空间控制(Ashkin, JM Dziedzic, JE Bjorkholm, S. Chu. Observation of a single-beam gradient force opticaltrap for dielectric particles. Opt. Lett. 1986, 11,288-290.),同时也促进了光致旋转的发展。 Since 1986 Askin et al proposed a "optical tweezers" to achieve a three-dimensional control of the particle (Ashkin, JM Dziedzic, JE Bjorkholm, S. Chu. Observation of a single-beam gradient force opticaltrap for dielectric particles. Opt. Lett. 1986, 11,288-290.), but also promoted the development of light-induced rotation. 到目前为止实现光驱动旋转主要采用如下几种方式:第一种方式是利用自旋角动量实现旋转;第二种方式是利用轨道角动量实现旋转;第三种方式是利用光的线性动量实现旋转,设计制作具有特定外形结构的微型器件,利用器件对光束的反射、折射、吸收等相互作用来实现器件的旋转(Galajda P,Ormos P. Complex Micromachines Produced and Driven by Light.App1.Phys.Lett.2001, 78(2) :249-251) 0利用第三种方式实现旋转的研究比较多,由于微粒的转速与方向可以人为控制,并且利用双光子聚合技术可以加工出适合于光学驱动的任意三维微器件,使得这种实验方法实现起来更加灵活,因此,目前有更多的研究人员致力于马达设计研究和改良。 So far mainly driven to rotate light to achieve the following ways: The first way is to use the spin angular momentum effect rotation; second way is the use of orbital angular momentum effect rotation; third embodiment is implemented using light of linear momentum rotation, the micro device having a specific design shape structure, the use of the device the reflected beam, refraction, absorption interaction effect rotation of the device (Galajda P, Ormos P. Complex Micromachines produced and Driven by Light.App1.Phys.Lett . 2001, 78 (2): 249-251) using a third embodiment of rotating 0 to achieve more, since the rotational speed and direction of the particles may be artificially controlled, and with two-photon polymerization techniques can be processed in any suitable optical drive three-dimensional micro-devices, making this experimental method to achieve more flexible, therefore, there are more researchers dedicated to research and improved motor design.

[0004] 匈牙利科学院的Ormos小组在这方面也做了大量的研究工作,提出了多种特殊形状的转子并通过实验进行了验证,利用激光光镊俘获并驱动螺旋形结构的转子,包括螺旋桨形,螺旋线形,洒水器形,经过实验验证对比在相同条件下螺旋桨形转子可以获得更高转速,IOmw的功率下可达到几赫兹的旋转速率(Peter Galajda, Pal Ormos. Rotation of microscopic propellers in lasertweezers. Journal of Optics B :Quantum and Semiclassical Optics 2002,4 (2),pp. S78-S81);为了得到连续的旋转控制方式,Ormos等人根据扁平粒子被产生线偏振光的激光光镊俘获旋转后,旋转方向与偏振面方向一致,因此设计了带有横截面为十字型齿轮粒子,虽然旋转方向易控制,但是相同的条件下产生的扭转力矩较小;另外,为了获得更好的实验结果,Ormos与他的同事又提出将多个转子组合形成齿轮带动装置,利 [0004] Ormos group Hungarian Academy also a lot of research work in this area, various special shape rotor proposed and verified by experiments, using a laser trapping and optical tweezers driven rotor helical structure, comprising a propeller type , helical, Sprinklers shape, through comparison of experimental verification propeller rotor can get a higher speed in the same conditions, the power can be achieved under IOmw rotation rate of several Hertz (Peter Galajda, Pal Ormos. rotation of microscopic propellers in lasertweezers. Journal of Optics B:. Quantum and Semiclassical Optics 2002,4 (2), pp S78-S81); a laser in order to obtain a continuous rotation control mode, and others of Ormos linearly polarized light is generated in accordance with the optical tweezer trap splat rotation, coincides with the rotational direction of the polarization plane direction, so the design of a cross-shaped cross section with a gear particles, although easy to control the rotational direction, but a small twisting moment generated under the same conditions; Furthermore, in order to obtain better results, of Ormos and his colleagues suggests they be combined to form a plurality of rotor gear drive unit, profit 中心转子转动带动其它转子。 Center of rotation of the rotor drives the other rotor. 考虑到激光光镊装置的复杂性,在某些应用下使用波导光驱动更有益,尤其在微流系统中,于是他们又提出了集成系统,包括光转子,光轴和利用双光子聚合方法形成的光波导,波导光输入功率IOmw可以产生2rps旋转速率。 Given the complexity of optical tweezers apparatus, an optical drive using a waveguide is more beneficial in some applications, particularly in a microfluidic system, and they also proposed integrated system, comprising a light rotor, and the axis formed by two-photon polymerization process an optical waveguide, the waveguide optical input power may be generated 2rps IOmw rotation rate.

IEEEJournal of Selected Topics in Quantum Electronics on Optical MEMS, 8, pp. 111-117,2002.),通过理论计算光力矩和粘性阻力,并且通过实验进行了验证。 [0005] Japanese Ritsumeikan University Ukita group also proposed various structures such as a simple rotor-like shuttlecock, shuttlecock beveled shape including three wings, and a plurality of wings and four wings beveled cylindrical structure a rotor (H.Ukita, Μ.

IEEEJournal of Selected Topics in Quantum Electronics on Optical MEMS, 8, pp. 111-117,2002.), calculate a light viscosity resistance torque and the theoretical and experimentally verified. 这些转子结构均能实现稳定俘获、高速旋转;同时通过理论计算和仿真光束的各个参数如光强、数值孔径、焦距等对转子的转速影响,从而优化了光束特性和转子结构。 These stable rotor structure can achieve capture, high-speed rotation; the same time through theoretical calculation and simulation of various parameters such as beam intensity, the numerical aperture of impact, the focal length of the rotor speed to optimize the characteristics of the beam structure and the rotor. Ukita等人考虑到微流系统中粘滞阻力的影响,提出了在带有斜面的转子的侧面制成圆柱形可以减少粘滞阻力,从而获得了更高的转速和性能。 Ukita et al consideration of the influence of the viscous resistance of a microfluidic system is proposed in the beveled side surface of a cylindrical rotor made of viscous drag can be reduced to obtain a higher speed and performance. 为了在微流系统中能够充分发挥搅拌器的作用,他们又提出了通过置换激光光镊光阱的位置来实现转子的逆时针和顺时针方向的变化,首先将两个带有三个翼的转子连接起来,经过激光照射整体,获得的转速为单一转子的2倍。 In order to give full play a stirrer in a microfluidic system, they also proposed to achieve a change in direction of the rotor counterclockwise and clockwise position of substitution by optical tweezers optical traps, two first rotor with three blades connected together integrally by laser irradiation, the rotational speed is twice to obtain a single rotor. 基于这种设计原理,Shoii Maruo等人也设计了一种组合式转子,将具有相反方向翼的两个转子联系起来,并且在两个转子外面套一个圆柱形外罩,目的是固定两个转子和减少粘滞阻力,然后将激光光束聚焦到两个转子的中间,使得作用到转子翼的光压力方向相同,因此增加了光扭转力矩,可以获得较高的转速。 Based on this design principle, Shoii Maruo et al also a modular design of the rotor, the rotor having two blades in opposite directions link, and a cylindrical sleeve housing on the outside of the two rotors, the two rotors are fixed object and reducing the viscous resistance, and focus the laser beam to the middle of the two rotors, such that the same optical pressure acting direction of the rotor blade, thus increasing the light twisting moment, higher speeds can be obtained.

[0006] Queensland大学Vincent LY Loke为了将光马达更好的应用到生物应用中,可以随时控制样本溶液的流动方向和位置,设计并利用双光子聚合技术制备了形状类似于®铃状中间带有叶片的转子,在多光束驱动下实现转动,获得了较高的搅拌效率。 [0006] Queensland University Vincent LY Loke order to better light applied to the motor biological applications, can always control the flow direction and the position of the sample solution, designed and prepared using a shape similar to the two-photon polymerization techniques with a bell-shaped intermediate ® rotor blades, in the multi-beam effect rotation of the drive was a high stirring efficiency.
