Specific embodiment
It illustrates with reference to the accompanying drawing and the present invention is discussed in more detail.
A kind of optical drive vibrating motor device based on optical fiber, including the first optical fiber source 1, the second optical fiber source 2, optical fiber
Wavelength division multiplexer 3, single mode optical fiber 4, absorbability black ball 5, liquid 6, by the outgoing of the first optical fiber source 1 and the second optical fiber source 2
End is welded with the incidence end of optical fibre wavelength division multiplexer 3 simultaneously, the exit end of optical fibre wavelength division multiplexer 3 and one end of single mode optical fiber 4
Welding, can motivate the Gauss light field of Stable distritation in the other end of single mode optical fiber 4.The device course of work: the first optical fiber is opened
Such as 980nm light source of light source 1, the side heat absorption that particle is irradiated by light differ particle two sides temperature, photophoresis caused by temperature gradient
Power moves particle to the direction far from light source.Particle in the process of movement, since inside particles thermal diffusion makes particle two sides
The temperature difference of temperature becomes smaller, and at this moment photophoresis power caused by different thermal accommodation coefficients accounts for leading, makes particle to lamp motion, until particle
Move to but generate certain temperature difference after repeat above-mentioned movement reach vibrating effect.Open the second optical fiber source 2 such as 1550nm light
Source, the second optical fiber source 2 are different from the first optical fiber source 1, this wave band light source can have an impact solution temperature, cause whole molten
The liquid coefficient of heat conduction changes, and the power of absorbability black ball in the movement direction can also change, so as to reach to frequency
The effect of rate control.
First optical fiber source 1 and the second optical fiber source 2 has stable output wavelength, and power can change, with
Ensure that the Gaussian beam generated can be stablized and change the position of absorbability black ball and amplitude in liquid, wherein the first optical fiber source 1 is such as
The wavelength of 980nm light source is the absorption peak of absorptive particles, and is not the absorption peak of fluid matrix, thus it is possible to vary absorbability black ball
Position, the wavelength of the second optical fiber source 2 such as 1550nm light source is the absorption peak of fluid matrix, to change the vibration of absorbability black ball
Dynamic frequency.
The single mode optical fiber 4 is OFS980 single mode optical fiber, and fiber end face is planar end surface.
The diameter range of the absorbability black ball 5 is 6-10 μm, is inhaled to the first optical fiber source 1 and the second optical fiber source 2
It receives；
The liquid 6 to the second optical fiber source 2 absorb without pair or seldom to the first optical fiber source 1 absorb, can be
One kind of glycerol mixture solution, ethylene glycol mixture solution or sucrose mixture solution etc., density are in 950kg/m3~
1350kg/m3In range, the coefficient of viscosity is 1 × 10-3[m2/ s]~2 × 10-3[m2/ s] in the range of.
A kind of optical drive vibrating motor device based on optical fiber, optical fiber 4 are embedded in the interior liquid for having absorbability black ball
In and after opening the light black ball occurs of reciprocating vibration being parallel to beam direction, adjusting 1 power of the first optical fiber source can change its position
It sets, adjusting 2 power of the second optical fiber source can change its vibration frequency.
Working principle is as follows:
For experiment in absorptive particles for, by gravity, the viscosity resistance of buoyancy and liquid, in a liquid by
Equilibrium state is in when stablizing capture in vertical direction, suffered viscosity resistance is along vertical direction.And the spoke that laser provides
Injection pressure and photophoresis power are parallel to light beam axial direction, and radiation pressure suffered by absorptive particles deviates from light source direction, the direction of photophoresis power
It is coaxial with radiation pressure.Effect when absorptive particles are irradiated with a laser by two kinds of photophoresis power, one is drawn by temperature gradient
It rises, another kind is as caused by different thermal accommodation coefficients.When the first optical fiber source 1 is opened, due to background liquid temperature
It is hardly influenced by the first optical fiber source 1, only absorptive particles absorb laser generation photophoresis power, and absorptive particles are molten with surrounding
The two kinds of photophoresis power transmitted between liquid dominate capture and axial vibration.For strong absorbent particle, had more in illumination side
The region high to laser power density from particle is pushed in heat absorption, therefore, a positive photophoresis due to caused by temperature gradient.
In conjunction with Fig. 1, gravity F in the vertical direction at this timeg, buoyancy FbIt is balanced with viscosity resistance F η three.Radiation pressure Frp
In the horizontal direction with photophoresis power, left side is due to the irradiation bead heat absorption of the first optical fiber source 1, so that there are temperature for bead two sides liquid
Difference, i.e. T1>T2Generate photophoresis power F caused by temperature gradient△T, the photophoresis power as caused by different thermal accommodation coefficients is F△α, F△T
>>F△αParticle is set to move right.
Particle is internal during the motion to be occurred heat exchange and keeps two sides temperature almost equal, when pushing away particle to particle two sides
Fluid temperature difference level off to 0 when so that because temperature gradient generate photophoresis power disappear substantially, so at this time by different acclimation to heats
Photophoresis power caused by coefficient accounts for leading, this photophoresis power is since the heat exchange of liquid and particle surface induces, its direction refers to
To for low direction from thermal accommodation coefficient height to thermal accommodation coefficient, particle configuration and surface characteristic are depended on, this power makes particle again
Move the photophoresis power that straight reason temperature gradient generates towards light source direction enhances to a certain extent again, repeats the above process later
Achieve the effect that vibration.
In conjunction with Fig. 2, gravity F in the vertical direction at this timeg, buoyancy FbIt is balanced with viscosity resistance F η three.Radiation pressure Frp
In the horizontal direction with photophoresis power, due to occur inside bead in motion process heat exchange keep particle two sides temperature difference very small so
F△TVery small, the photophoresis power as caused by different thermal accommodation coefficients is F△α, F△α>>F△TIt is moved to the left particle, is moved to F△T
Above-mentioned two processes are repeated after sufficiently large to reach vibrating effect.
When the second optical fiber source 2 such as open by 1550nm light source, what it is different from the first optical fiber source 1 is this wave band light source meeting
Solution temperature is had an impact, therefore whole solution thermal accommodation coefficient can change, absorbability black ball is in the movement direction
The size of power can also change, i.e., the photophoresis power as caused by different thermal accommodation coefficients is F△αIt changes, similarly, in conjunction with
Analysis before can play the effect to vibration frequency control.
In conjunction with Fig. 4, particle moves repeatedly in two circular dashed lines, and moving right speed is V, and moving downward speed is V ',
Changing 1 power of the first optical fiber source can change catch position, and changing 2 power of the second optical fiber source can change particle vibration vibration
Width.
