Specific embodiment:
Of the invention is described in detail with reference to the accompanying drawings and examples.
As shown in Figure 1, a kind of device that optical ultra-discrimination imaging is realized based on optical tweezer, it is characterized in that:
Laser 1 used in system is the fiber coupling solid-state laser 1 of 1064nm wavelength continuous wave output, laser
The light of 1 outgoing is directional light, power stability 2%~5%, the small 0.25mm of laser beam position stability.Optical fiber-coupled laser
It is that the laser head separated at one with laser pump (ing) excites, the temperature change of laser head is smaller, therefore the laser generated is usual
With extraordinary position stability.
The directional light that laser 1 is emitted expands laser perpendicular through the center of beam expander 2.Laser after expanding
It is reflected via Piezoelectric Driving reflecting mirror 3, and the rotation center of Piezoelectric Driving reflecting mirror 3 will be overlapped with incident light axis center.Swash
Light and the illumination light being emitted by LED light 4 pass through dichroscope 11 and are coupled into same optical path, and the wherein effect of dichroscope 11 is
Penetrate laser and indirect illumination light.Light after coupling enters object lens 5 through semi-transparent semi-reflecting lens 9, and laser forms ligh trap after focusing and is used for
Bead is captured, illumination light is used for optical imagery.Sample 6 is fixed on displacement platform 7, can be with mobile example by control bit moving stage 7
6.Reflected light reflects after returning to object lens 5 through semi-transparent semi-reflecting lens 9, the light beam after reflection by optical filter 8, reach CCD camera 10 into
Row imaging.Wherein the effect of optical filter 8 is to filter laser, only illumination light is allowed to pass through to protect CCD camera 10.
The method and apparatus for realizing super-resolution based on optical tweezer include following equipment and operation:
Step A: the collimation laser of height convergence and the object lens 5 of high-NA being emitted using laser 1 form one
The optical tweezer of high Optical Trap Stiffness, for capturing and mobile microballoon.
The optical tweezer of big Optical Trap Stiffness is formed by the object lens 5 of high-NA using the collimated laser beam of height convergence,
The laser beam is linear polarization Gaussian beam, the beam expander 2 being made of by one two lens, so having biggish light intensity
Gradient.
Step B: a set of visible light micro-imaging optical path suitable for optical optical tweezers system is built using CCD camera 10, using saturating
It penetrates light and carries out reflection micro-imaging.
Use LED light 4 as lighting source, optical tweezer optical path and illumination path have a part of some coincidences, in the present invention
A dichroscope 11 and semi-transparent semi-reflecting lens 9 have been used, have been individually positioned in front of the lighting source incidence object lens 5 and outgoing object
After mirror 5, for changing the direction of illumination light, and it is used to coupled illumination light and laser before by sample 6, is passing through sample
Separation incident light and emergent light after 6.Emergent light after separation only passes through illumination light, illumination light using an optical filter 8
For micro-imaging.
Step C: the solution of microballoon is had using the fixed sample to be tested 6 of displacement platform 7, and in sample surfaces injection.
If measuring environment is liquid environment, the solution of microballoon is just had in the drop of sample to be tested surface, then
It measures.If necessary to measure in air, need first to wait solution evaporation clean, then carry out subsequent measurement.
Step D: loading sample 6 and captures microballoon using optical tweezer, microballoon is placed on to the micro-structure surface for needing to measure, so
Image is obtained using micro-imaging optical path afterwards, passes through the surface of available 6 different location of sample of mobile example 6 and microballoon position
Structural images.
By moving displacement platform 7, the microballoon of sample surfaces is captured using optical tweezer, if it is the mobile microballoon of small distance,
It can be realized by the mobile ligh trap of Piezoelectric Driving reflecting mirror 3；If necessary to a wide range of mobile microballoon, then need to put by movement
Microballoon is placed on 6 surface of sample for needing to measure by the sample 6 set on displacement platform 7.Since microballoon realizes that super-resolution is not
In the focal point of object lens 5, so ligh trap position is not overlapped with imaging position, so temporary close laser is needed, then with aobvious
The micro-structure under microballoon is imaged in micro- imaging optical path, and the available size of CCD camera 10 is less than micro- knot of diffraction limit
The shape appearance figure of structure.
Step E: selecting the microballoon of different size and material to measure, finally obtain best imaging effect, to
The image arrived carries out post-processing.
The microballoon that diameter does not wait be can choose to measure, obtain the different image of resolution ratio, microsphere diameter gets over great achievement
Picture region is bigger, and the smaller imaging resolution of microballoon is higher.It is also an option that the microballoon of different materials, generally there are commonly titanium dioxides
The refractive index of silicon microballoon, different materials is different, so having a great impact to image quality.Measurement solution also can choose difference
Liquid have an impact since different solution refractive index are different to the size and imaging of trapping stiffness.It finally needs to spell by image
It connects algorithm to splice the image measured in different location, obtains measurement result to the end.
