Abstract
The utility model relates to a high resolution optic fibre passes image bundle. The utility model is composed of the composite filaments which are stacked and composed of the monofilaments. The utility model provides an optic fibre pass image bundle cross sectional area little, the big and low technical problem of resolution ratio of monofilament diameter.
Description
One, technical field:
The utility model relates to a kind of high-resolution optical fiber image transmission bundle.
Two, background technology
High-resolution optical fiber image transmission bundle is in scientific research, medical treatment and industrial, particularly military field has a wide range of applications, in military scouting periscope, antitank missile system and some precision detection instruments, all adopt the heavy in section optical fiber image transmission beam of high resolving power, resolution requirement is up to more than the 90lp/mm, and the cross section is more than 5 * 5mm.
The method that present optical fiber image transmission beam is commonly used has two kinds: layered manner and sour molten method.Layered manner is owing to the restriction of drawing process, and filament diameter generally can not be lower than 12um, otherwise brings very big difficulty to production.The molten method of acid is to be drawn into silk after the single fiber wire material is arranged in the composition fiber rod, use the soluble glass of sour eating away single fiber material outer layer again, can accomplish the video beam of filament diameter like this at 8～10um, but area of section generally can only be accomplished below the φ 3mm, because if the cross section is excessive, the soluble glass of video beam center section is because acid molten entering and can't not being corroded, and diameter adopts sour molten manufactured also very difficult less than the coherent fiber bundle of 8um, the wire broken rate height.
Three, utility model content
The utility model has solved the technical matters that the optical fiber image transmission beam area of section is little, filament diameter is big and resolution is low.
The technical solution of the utility model is: the utility model is a kind of optical fiber image transmission beam, and its special character is: described optical fiber image transmission beam comprises composite filaments, and the stacked setting of described composite filaments also has some monofilament in the composite filaments.
Above-mentioned composite filaments constitutes by monofilament is stacked.
Above-mentioned monofilament skin is a light, and inner core is a glass of high refractive index.
To contain monofilament in the above-mentioned composite filaments be 7, more than 19 or 37.
The stacked cross sectional shape of above-mentioned composite filaments is regular hexagon or square.
Above-mentioned monofilament is 7, more than 19 or 37.
The stacked cross sectional shape of above-mentioned monofilament is regular hexagon or square.
Above-mentioned filament diameter is 1.0～2.0mm, and the diameter of composite filaments is 12～40um.
The utility model is broken through the structure of traditional fiber coherent fiber bundle, earlier constitute composite filaments by the stacked after stretching of multifilament, again the many stacked after stretching of composite filaments are constituted optical fiber image transmission beam, contain some monofilament in this every stacked composite filaments, filament diameter has dwindled some/one than filament diameter in the video beam of common layered manner manufacturing like this, the resolution of whole video beam has improved several times, improve optical fiber image transmission beam resolution thus greatly, on the basis of having improved the optical fiber image transmission beam area of section, dwindled filament diameter simultaneously.
Four, description of drawings
Fig. 1 is the structural representation of the xsect of the utility model specific embodiment;
Fig. 2 is the structural representation of the composite filaments xsect of Fig. 1.
Five, embodiment:
The utility model constitutes by the above composite filaments of 7,19 or 37 1 is stacked, and composite filaments 1 constitutes by the above monofilament of 7,19 or 37 2 is stacked, and monofilament 2 skins are light, and inner core is a glass of high refractive index.Composite filaments 1 stacked cross sectional shape is regular hexagon or square.Monofilament 2 stacked cross sectional shapes are regular hexagon or square.Filament diameter is 1.0～2.0mm, and the diameter of composite filaments is 12～40um.
Referring to Fig. 1,2, the utility model embodiment is stacked for regular hexagon constitutes by 19 composite filaments 1, and this composite filaments 1 is to constitute for regular hexagon by 19 monofilament 2 are stacked.
