Description
Technical field
The present invention relates to fiber delay line field, and in particular to a kind of to adjust the high fiber delay line of stability.
Background technology
Nowadays, since optical fiber technology invention, the research and application of various optical fibre devices emerge in an endless stream.As new
For the fibre delay line FDL of signal processor from initial simple one section of optical fiber, develop into has Various Complex at this stage
The individual devices of structure, turn into one of Primary Component in optical information processing technology, there is multi-signal processing function, such as in light
Fibre sensing is with participating in realizing the collection of measurement signal and transmission, realizing signal in fiber optic communication systems in optical measuring system
Coding realizes that the precise phase distribution of microwave signal and control, radar return are believed with caching, in optically controlled phased array antennas system
Number correlation except making an uproar.
Existing fiber delayer is in order to ensure stability during optical directory elements movement, using sliding block to optically guiding member
Part is fixed, and sliding block is fastened on guide rail, and when motor driving sliding block moves, 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 in it：Reach sliding first, being set by the card of guide rail and sliding block
, there is gap in the stable mobile purpose of block, in moving process, the gap can also influence sliding block movement between guide rail and sliding block
Stationarity, the stability rocked and can influence optical directory elements is produced, influence the adjustable accuracy of fiber delay line；It is second, logical
The gap overregulated between guide rail and sliding block can adjust the stability of sliding block movement, but due to technology restriction, be now to use
The guide rail and slide block structure of high matching degree, both, which are both needed to import, could meet to require, the material of domestic supply is undesirable, its
It is costly.
The content 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：
It is a kind of to adjust the high fiber delay line of stability, including guide and the sliding block for fixing optical directory elements,
Bearing is fixed with the sliding block, the bearing is socketed on guide, and the guide is into tubular, the barrel of the guide
On its diametric(al) is provided with gap, the both sides in the guide gap have the trend of outside opening.Bearing is fixed on
On sliding block and it is socketed over the guide, now the gap very little between bearing and gap；Guide is into tubular and is provided with gap,
The both sides in the gap have the trend of outside opening, i.e. guide has stress, and the stress makes guide further be adjacent to
Bearing, it is further to reduce the distance between guide and bearing, the stability of sliding block movement is improved, that is, improves optically guiding member
The moving stability of part, improve the adjustable accuracy of fiber delay line.Using said structure, its is simple in construction, not by technology restriction,
It is easy to make and cost is cheap.
Preferably, in order to improve the stability of guide fixation, in addition to U-shaped fixture, the both ends of the guide
It is fixed on the two side of U-shaped fixture.Guide is fixed from both ends, the stability of guide fixation can be improved；And
Using U-shape structure, it is easy to be fixedly mounted.
Further, in addition to motor and the screw mandrel that is connected on motor output shaft, the sliding block are socketed in by screw thread
On screw mandrel, for the ease of the fixation of motor, motor is fixed in a side wall of U-shaped fixture by pinboard.Existing motor
It is fixed by bonding, it is not only not easy to assemble, and the stability that motor is fixed can also be affected.This programme is by turning
Motor is fixed on U-shaped fixture by fishplate bar, is not only convenient for assembling, and motor can be fixed by bolt, strengthen motor
Stability.
Further, in order to improve stationarity during sliding block movement, the guide has two and is located at screw mandrel two respectively
Side.Guide carries out limition orientation from screw mandrel both sides to it, higher compared to one-sided configuration, its stability.
Further, in order to improve the degree of regulation of light delay device, precision regulating is provided with the screw mandrel.
Further, the precision regulating includes block and the spring being enclosed on outside screw mandrel, the block and screw mandrel spiral shell
Line connects, and the spring is between block and sliding block.The screw mandrel that is moved through of sliding block rotates promotion, has between sliding block and screw mandrel
There is gap, it influences degree of regulation.This programme is in the spring of screw mandrel overcoat one, and spring has thrust to block and sliding block, in thrust
Operation under, can reduce has gap between sliding block and screw mandrel, so as to improve adjustable accuracy.
The present invention compared with prior art, has the following advantages and advantages：
1st, the cooperation of guide and bearing of the present invention has the function that guiding, and guide has gap, and gap both sides have
There is the trend of opening, the trend power can promote guide to be adjacent to bearing, reduce the distance between guide and bearing, improve sliding block
Mobile stability, improve the adjustable accuracy of fiber delay line.
2nd, the compactness between of the invention guide and bearing is realized by the stress of guide, compared to leading accordingly
Rail structure, its technical requirements is low, and simple in construction, and cost is cheap.
