Description
Technical field:
The present invention relates to industries such as safety check, detective, medical treatment, chemical industry, be used for the be beyond one's reach look-out at poisonous and harmful and extremely narrow and small position of routine inspection human eye.
Background technology:
Along with developing rapidly of Chinese national economy, endoscope has been widely applied to the every field of national economy.Because optical fiber has anti-electromagnetic interference (EMI), characteristics such as corrosion-resistant, soft flexible receive the favor of many occasions for this reason, the human eye look-out at poisonous and harmful and extremely narrow and small position that is beyond one's reach especially, and just the superfine fibre opic endoscope of needs can be operated.What the present invention adopted is ultra-fine silica fibre coherent fiber bundle, and the silk footpath of simple optical fiber directly affects the resolution of system in the coherent fiber bundle, and the diameter of coherent fiber bundle and GRIN Lens directly influences the size of the size of system's insertion portion.
Use customs's safety check to be example with alert, carry suspicious item secretly, with common fibre opic endoscope, because the diameter of optical fiber facsimile beam slightly can't Direct observation as suspecting in parcel, the envelope etc.Ordinary optic fibre endoscope method for making is to adopt the spherical optical lens group as object lens (1), uses many components glass coherent fiber bundle (2) of being made up of up to ten thousand loose spun glass, and the outside is with the layer of protecting pipe.An end face of many components glass coherent fiber bundle (2) is fixed on through metal connecting piece (3) near the focal length face of object lens (1).Optical fibre ring is passed light beam (4) be bonded in metal connecting piece (3); External light source (9) passes light beam (4) through optical fibre ring and imports light into and illuminating objects; Many components glass coherent fiber bundle (2) takes out picture, and through imaging eyepiece (5), CCD chip (6) is with image-capture; Be connected with exterior display screen (8) through connecting line (7), play the effect of keeping watch on of observing.Because many components glass coherent fiber bundle (2) front end insertion portion diameter is thick, can't survey extremely narrow space.The ordinary optic fibre endoscope adopts external light source, exterior display screen, and volume is big, and weight is big, is not easy to carry, and is not suitable for on-the-spot the detection and uses.
Summary of the invention:
The objective of the invention is to make a kind of employing GRIN Lens, silica fibre coherent fiber bundle, and with the ultra-violet curing optical cement with the two direct bonding fibre opic endoscope, the insertion portion diameter is smaller or equal to 2mm, can use at narrow space extremely.The present invention is integrated with light source, display screen, and volume is little, in light weight, is fit to on-the-spot the use, has improved work efficiency greatly.GRIN Lens is the good passive device of a cylindrical two ends grinding and polishing; Corresponding one by one arrangement the in two ends that the silica fibre coherent fiber bundle is made up of up to ten thousand thin optic fibre silks; The thin rod that is melted in one that the end surface grinding polishing is good; Its effective diameter is smaller or equal to 0.8mm, and the diameter of diameter and GRIN Lens is all smaller or equal to 1mm after the coherent fiber bundle coating organic gel.
But a kind of thin diameter hand-held monitoring fiber endoscope provided by the invention; Comprise GRIN Lens (1), silica fibre coherent fiber bundle (2), the coupling optical glue (3) between GRIN Lens (1) and the silica fibre coherent fiber bundle (2); GRIN Lens (1) passes light beam (4) with the outer bonding optical fibre ring of silica fibre coherent fiber bundle (2); Imaging eyepiece group (5), CCD chip (6), handle (7); Light source (8) and monitor screen (9).It is characterized in that: between described GRIN Lens (1) and silica fibre coherent fiber bundle (2), use coupling optical glue (3) to be connected.Coupling optical glue (3) is refractive index ultra-violet curing optical cement between 1.55-1.65, needs to use ultraviolet curing lamp to solidify.Peripheral direct bonding annular passes light beam (4), and optical fibre ring passes the external diameter of light beam (4) smaller or equal to 1.7mm, and the bonding optical fibre ring passes the process of light beam and can keep watch at display screen.
But the preparation method of described thin diameter hand-held monitoring fiber endoscope is characterized in that, may further comprise the steps:
With the coaxial clamping of GRIN Lens and optical fiber image transmission beam, the end face clearance distance is inserted coupling optical glue smaller or equal to 0.05mm in the slit between the two, solidifies after 1-10 minute, and GRIN Lens and optical fiber image transmission beam become one.The peripheral bonding of GRIN Lens that will become one again and coherent fiber bundle optical fibre ring passes light beam, and optical fibre ring passes the external diameter of light beam smaller or equal to 1.7mm, and the bonding optical fibre ring passes the process of light beam and can keep watch at display screen.After optical fibre ring passed light beam end surface grinding, polishing, pass the light beam outside at optical fibre ring and be with protection tube.The protection tube external diameter is smaller or equal to 2mm.
There is fixed support that display screen directly is fixed on the handle on the handle.
The principle of the invention is: light collects on the other end after a branch of directional light is through the GRIN Lens of 1/4 pitch.It is big that quartz material and many components glass material are compared its elastic modulus, and applying the back diameter can soft bending smaller or equal to the silica fibre coherent fiber bundle of 1mm.Optical fiber image transmission beam is the coherent optical-fiber element; Can undistortedly must be delivered to the other end to the picture of an end; Minimum air gap between GRIN Lens and the coherent fiber bundle end face is filled up by the optical cement of refractive index between 1.50-1.60; Because the refractive index of the material at its refractive index and two ends is close, its transmitance loss is little, and can both be solidified togather through the irradiation of ultraviolet light.
