Description
Technical field
Picture flexible optical circuit, particularly multi-disc lens group are passed the present invention relates to one kind by mechanical gimbals to be connected to realize
The flexible biography that multiple degrees of freedom is rotated and formed can replace image-carrying fiber bundle to be used for the undistorted of image in crooked pipeline as light path
High-resolution is transmitted.
Background technology
In order to realize the undistorted transmission of image in bent tube form structure, usual way is to use image-carrying fiber bundle
（Imaging optical fiber bundle）.Image-carrying fiber bundle is with illumination fiber optic bundle by up to thousands of to tens thousand of optical fiber
Composition.The optical fiber arrangement at image-carrying fiber bundle both ends is identical, wherein every optical fiber corresponds in the position at both ends, makes biography picture
The image of fibre bundle side can completely be transferred to the opposite side of image-carrying fiber bundle without distortion；And the light at illumination fiber optic bundle both ends
Fibre arrangement is entirely different, has upset completely during the opposite side of the image transmitting of illumination fiber optic bundle side to image-carrying fiber bundle, because
This illumination fiber optic bundle is only used for illuminating.
The advantages of image-carrying fiber bundle is that diameter is small, has certain flexible（For both ends and the middle biography picture all bonded
Fibre bundle depends on the parameter such as diameter, quantity of simple optical fiber；Bonded for both ends, scatter the image-carrying fiber bundle not bonded for centre
This problem is then not present）The advantages that.But there is also many shortcomings for image-carrying fiber bundle：1. processing technology is complicated, cost is higher；2.
In the presence of certain wire broken rate, long-term use influences image quality；3. can not high-quality transmission ultrashort pulse, lead to not by with
It is imaged in nonlinear optics：Common nonlinear optical effect includes double/three-photon and excites fluorescence（Two/Third-photon
Excited Fluorescence, TPEF/Third PEF）, two-photon excitation autofluorescence（Two-photon Excited
Autofluorescence,TPEAF）, the generation of two/triple-frequency harmonics（Second/Third Harmonic Generation,SHG/
THG）, coherent anti-stokes raman scattering (Coherent Anti-Strokes Raman Scattering, CARS) etc..
These nonlinear optical effect generally use femtosecond lasers or picosecond laser are as excitation source.Excitation source is sent ultrafast sharp
Light pulse is transmitted mainly by Self-phase modulation in the optical element such as ordinary optic fibre and lens（Self Phase
Modulation, SPM, it is relevant with light intensity）With group velocity delay (Group Velocity Delay, GVD) both effects
Influence and broadening.Image-carrying fiber bundle is made up of thousands of to tens thousand of single-mode fibers, because the diameter of every single-mode fiber is only to count
Micron, pulsewidth 100fs energy 10nJ laser pulse pass through 1cm length due to self phase modulation in single-mode fiber
1-10ps is just stretched to, peak energy substantially reduces.Energy is stronger, and self phase modulation is more obvious, and is difficult compensation.Exhibition
Laser pulse after width continue to propagate in a fiber can based on broadening that group velocity delay effect is brought, and this broadening be can
With what is compensated.The laser pulse of broadening can substantially reduce the launching efficiency of nonlinear effect.Although therefore image-carrying fiber bundle
It is burnt to have been used for the copolymerization that single photon fluorescence excites（Confocal）Based endoscopic imaging, and it is not used to nonlinear optics imaging.
4. imaging resolution is low：Using the optical imaging system of image-carrying fiber bundle resolution ratio=（Adjacent two single modes in image-carrying fiber bundle
The spacing of fiber optic hub）* the numerical aperture of numerical aperture/image-carrying fiber bundle of object lens, adjacent two in common image-carrying fiber bundle
For the spacing minimum at root single-mode fiber center in 3um or so, the numerical aperture of image-carrying fiber bundle is about 0.5 or so, and by passing as light
The limitation of the application of fine beam, object lens can not often use desk-top microscopical standard high-NA objective, can only use small
The miniature object lens of diameter, its numerical aperture are up to 0.5-0.8 or so, therefore use the optical imaging system of image-carrying fiber bundle
Resolution ratio is usually 2-3um, indivedual minimum 1.0um（Such as French Cellvizio GastroFlex UHD）；5. it is imaged as
Latticed, it is necessary to which later image is handled, image quality is low, signal cross-talk between adjacent fiber be present, material between adjacent fiber
Easily it is excited and produces fluorescent noise etc..
In order to solve above mentioned problem existing for image-carrying fiber bundle, present invention employs multi-disc lens group to pass through mechanical gimbals
It is connected the flexible biography formed to realize multiple degrees of freedom to rotate as light path, image-carrying fiber bundle can be replaced to be used to scheme in crooked pipeline
The undistorted high-resolution transmission of picture.
