Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a system for height alignment and inspection of optical fibers,

The present invention relates to a system for performing height alignment of a processed optical fiber and defect inspection of the optical fiber, which realizes the same height of each optical fiber by automatically aligning the height of the optical fiber, and enlarges individual images The present invention relates to a system for height alignment and inspection of an optical fiber for detecting defects of an optical fiber cross-section.

In general, the height of the optical fiber exposed from the ferrule must be the same before delivery of the processed optical fiber, and it is also necessary to check the optical fiber cross-sectional defect.

If the height of the optical fiber is not adjusted, or if the optical fiber is delivered without confirming the cross-sectional defect of the optical fiber, various problems such as a data transmission error and a transmission speed decrease are caused in the optical communication field .

In addition, there is no way to confirm whether the optical fiber cross-section is bad (crack, hole, contamination, scratch) with the naked eye.

On the other hand, disclosed in Japanese Patent Application Laid-Open Nos. 10-2005-0080854 (Patent Document 1), Published Patent Application No. 10-2011-0070598 (Patent Document 2) and the like are disclosed as techniques related to inspection of optical fibers.

In the case of Patent Document 1, a technology of a base material inspection apparatus for an optical fiber includes a motor for rotating the optical fiber preform at a constant peripheral speed, a first light source for irradiating the first light in parallel with the long axis of the optical fiber preform, And a second light source for irradiating the second light in parallel with the short axis of the optical fiber preform, and a second light source for irradiating the second light in parallel with the short axis of the optical fiber preform, And a second detector for reciprocating left and right along the major axis of the optical fiber preform and for detecting the geometry of the optical fiber preform from the second light having passed through the minor axis of the optical fiber preform.

The technique of Patent Document 1 has an advantage in that the state of the inside of the optical fiber preform can be accurately inspected and measurement of the geometrical structure such as the diameter of the base material and the length of the long axis can be performed.

However, since only the level of inspection of the internal state of the optical fiber is maintained, it is impossible to detect minute defects (cracks, holes, contamination, scratches) on the cross section of the optical fiber, and the same height adjustment of the optical fiber can not be realized I can not solve it.

On the other hand, in the case of Patent Document 2, as a portable optical cable inspecting device technology, there is a portable optical cable inspecting device having a single optical fiber adapter in which an optical cable is inserted, an optical output measuring device for measuring an output of an optical signal transmitted through an optical cable inserted in the optical cable adapter, Sectional image of the optical cable inserted into the adapter, and an optical signal transmitted through the optical cable and a light beam representing a cross-sectional image of the optical cable, the optical signal being transmitted to the optical power measuring device, And a display unit for displaying an output of the optical signal measured by the optical output measuring device and a sectional image of the optical cable taken by the imaging unit .

In the case of the above Patent Document 2, it is possible to confirm the contamination of the optical fiber with respect to the cross section, and it is possible to carry out inspection in a portable state on the field, thereby providing convenience and convenience of workability.

However, it is impossible to construct a defect in the cross section of the optical fiber by the database, and the height adjustment of the optical fiber can not be realized, and fundamentally the technical constitution part differs from the system constitution part of the present invention.

[

The detection unit 41 vertically descends in the direction of the fixed base 21. At this time, the electron microscope 44 of the detection unit 41 detects the alignment jig 50, which is seated on the fixed base 21, The inspection of the cross section of the optical fibers (OF) aligned in the optical fibers (OF) is detected.

In the process of inspection of the section of the optical fiber (OF) of the detection unit 41, a process to be performed by the operator is described in detail in the above, so that an additional description will not be given, and an optical fiber detection algorithm, Will be described.

Optical fiber detection algorithm

After the image of each cross section of the optical fiber OF is obtained through the electron microscope 44 of the detection unit 41, the presence or absence of the optical fiber OF is checked through image processing. In view of the diameter characteristics of the optical fiber OF, Ø125um), it compensates for the machining error and the fixed error of the jig, and scans the optical fiber (OF) by the set position reference. The optical fiber detection range may be approximately 800 μm × 560 μm.

That is, the optical fiber detection algorithm is a function to compensate for the jig machining error, and it performs the function of scanning the periphery of the predetermined position in order to measure the optical fiber having the diameter of 125um.

Paralel check algorithm

It is possible to confirm that an empty space is inset in the insertion holes 52 and 62 of the alignment jig 50 or the polishing jig 60 during the image collection progress and that the inspection time is excessively consumed because the optical fiber detection algorithm is not applied Prevention.

Display (display) screen on the monitor 120 according to the presence /

When the alignment jig 50 or the polishing jig 60 is applied, if there is no ferule P, the corresponding optical fiber (OF) number of the marking unit 122 played on the monitor 120 is displayed in red, In one place, the ferrule (P) exists and the corresponding optical fiber (OF) number is indicated in yellow.

That is, when image collection for each cross section of the optical fiber OF through the electron microscope 44 of the detection unit 41 is completed, the jig (alignment jig or polishing jig) is automatically moved to the loading position, (About 5 seconds) The display of the tower lamp can save or delete the individual cross-sectional images of the collected optical fibers (OF) to the data storage unit 100 as the program is activated on the monitor 120,

When the inspection of the optical fiber OF through the detection unit 41 is performed, for example, the optical fibers OF are aligned from No. 1 to No. 64 as listed in the marking unit 122, Sectional image of the optical fiber (OF) corresponding to the next No. 2 is collected, and the sectional image of the optical fiber (OF) corresponding to the next No. 2 is collected, and the optical fiber (OF) ). ≪ / RTI >

When the alignment jig or the polishing jig is selected and used, the illumination adjuster 150 performs a cross-sectional inspection of the optical fiber OF by differently adjusting the illumination intensity of the electron microscope 44. However, If the illumination intensity is not adjusted, the defective state of the optical fiber (OF) cross section can not be detected.

The operation control unit 140 includes an end button for terminating all processes of the system, loading the system at an initial setting position or performing a system standby, and an emergency button As shown in FIG.
