Description
Technical field
The present invention relates to fiber delay line fields, and in particular to a kind of to adjust the high fiber delay line of stability.
Background technique
Nowadays, since optical fiber technology invention, the research and application of various optical fibre devices emerge one after another.As novel
For the fibre delay line FDL of signal processor from initial simple one section of optical fiber, develop to has Various Complex at this stage
The individual devices of structure become one of the Primary Component in optical information processing technology, have multi-signal processing function, such as in light
Signal is realized in fibre sensing and the acquisition and transmission for participating in realizing measuring signal in optical measuring system in fiber optic communication systems
Coding realizes that the precise phase distribution of microwave signal is believed with control, radar return with caching, in optically controlled phased array antennas system
Number correlation except making an uproar.
Stability when existing fiber delayer is in order to guarantee that optical directory elements are mobile, using sliding block to optically guiding member
Part is fixed, and sliding block is fastened on guide rail, and when motor driven sliding block is mobile, guide rail play the guiding role to sliding block, to reach steady
Surely the purpose moved.But using this kind of mode, there are two defects: reaching sliding first, setting by the card of guide rail and sliding block
Block stablizes mobile purpose, and there are gaps between guide rail and sliding block, and in moving process, which also will affect sliding block movement
Stationarity generates the stability shaken and will affect optical directory elements, influences the adjustable accuracy of fiber delay line；Second, logical
Overregulate gap between guide rail and sliding block and the mobile stability of sliding block be adjusted, but due to technical restriction, be now to using
The guide rail and slide block structure of high matching degree, the two, which is both needed to import, can just meet the requirements, and the material of domestic supply is undesirable,
It is costly.
Summary of the invention
In order to solve the above-mentioned technical problem the present invention provides a kind of fiber delay line.
The present invention is achieved through the following technical solutions:
A kind of fiber delay line that adjusting stability is high, the sliding block including guide part and for fixing optical directory elements,
Bearing is fixed on the sliding block, over the guide, the guide part is at tubular, the barrel of the guide part for the bearing socket
On had the gap along the setting of its diametrical direction, the both sides in the guide part gap have the trend of outside opening.Bearing is fixed on
It on sliding block and is socketed over the guide, at this time the gap very little between bearing and gap；Guide part has the gap at tubular and setting,
The both sides in the gap have the trend of outside opening, i.e. guide part has stress, which be adjacent to guide part further
Bearing, it is further to reduce the distance between guide part and bearing, improve the mobile stability of sliding block, i.e. raising optically guiding member
The moving stability of part improves the adjustable accuracy of fiber delay line.Using the above structure, structure is simple, not by technical restriction,
It is easy to make and low in cost.
Preferably, further including U-shaped fixing piece, the both ends of the guide part to improve the fixed stability of guide part
It is fixed on the two sidewalls of U-shaped fixing piece.Guide part is fixed from both ends, the fixed stability of guide part can be improved；And
Using U-shaped structure, convenient for being fixedly mounted.
Further, the screw rod for further including motor and being connected on motor output shaft, the sliding block are socketed in by screw thread
On screw rod, for the ease of the fixation of motor, motor is fixed in the one side wall of U-shaped fixing piece by pinboard.Existing motor
It is fixed by bonding, is not only not easy to assemble, and the stability that motor is fixed also will receive influence.This programme is by turning
Motor is fixed on U-shaped fixing piece by fishplate bar, is not only convenient for assembling, and motor can be fixed by bolt, enhance motor
Stability.
Further, in order to improve stationarity when sliding block movement, the guide part has two and is located at screw rod two
Side.Guide part carries out limition orientation to it from screw rod two sides, and compared to one-sided configuration, stability is higher.
Further, in order to improve the degree of regulation of light delay device, precision regulating is provided on the screw rod.
Further, the precision regulating includes block and covers the spring outside screw rod, the block and screw rod spiral shell
Line connection, the spring is between block and sliding block.The movement of sliding block is rotated by screw rod and is pushed, and is had between sliding block and screw rod
There is gap, influences degree of regulation.This programme is in one spring of screw rod housing, and spring has thrust to block and sliding block, in thrust
Operation under, can reduce between sliding block and screw rod have gap, to improve adjustable accuracy.
Compared with prior art, the present invention having the following advantages and benefits:
1, the cooperation of guide part and bearing of the present invention has the function that guiding, and guide part has gap, and gap both sides have
Has the tendency that opening, which can push guide part to be adjacent to bearing, reduce the distance between guide part and bearing, improve sliding block
Mobile stability improves the adjustable accuracy of fiber delay line.
2, the compactness between guide part and bearing of the invention is realized by the stress of guide part, compared to leading accordingly
Rail structure, technical requirements are low, and structure is simple, low in cost.
