The present embodiment has the advantage that
By the setting of light loss slot 12, so that photocon 11 is bent and light loss slot 12 is located at photocon
11 bending peripheries side when, can by light loss slot 12 influence optical path geometrical model so that the geometrical model of optical path and
The geometrical model of bending loss oscillatory occurences mismatches, thus loss oscillatory occurences when eliminating macrobending.Therefore, at this
The luminous flux of photocon 11 is in monotone variation in a bending process.Also, photocon 11 is from straightened condition to single direction
During curved, or during extending to straightened condition along single direction from curved state, luminous flux is also all in
It is monotonically changed.
When the sensor is in natural shrinking state, photocon 11 is bent and light loss slot 12 is located at light guide member
The side that part 11 is bent periphery causes the light of the specific incidence angle in part from light loss slot since there are light loss slots 12
12 escape cortexes and dissipate, so that sensor luminous flux of some when being in natural shrinking state is depleted.When tested
Object struts sensor, so that sensor is in open configuration, and photocon 11 is made to tend to straightened condition, to make light
The surface of loss slot 12 is compressed and to be gradually intended to light loss slot 12 parallel with input path, has less light from light
Loss slot 12 escapes cortex and dissipates, and increases luminous flux, and the variation of luminous flux is in monotone variation.
When measured object week diameter reduces, elastic base 23 drives the rebound of photocon 11 to shrink, and makes photocon
11 tend to be bent to the direction far from light loss slot 12, so that the surface of light loss slot 12 be made to be stretched and gradually be intended to
Light loss slot 12 is vertical with input path, has more light to escape cortex from light loss slot 12 and dissipate, makes luminous flux
It reduces, and the variation of luminous flux is in monotone variation.
The sensor is either flared out or to contract, and the light flux variations of photocon 11 are in monotone variation
, and this variation is consecutive variations, and the bending degree of measured object is judged so as to the luminous flux by photocon 11.
The depth of each opening portion in the light loss slot 12 of photocon 11 is smaller than the radius of photocon 11 by one
A order of magnitude, when photocon 11 is bent and light loss slot 12 is located at the outer peripheral surface of bending direction, the overall damage of luminous flux
Consumption is Approximate Equivalent in being superimposed macrobending loss and microbending loss, therefore when this bending occurs, the variation of luminous flux is
Significantly, it ensure that sensor has very high sensitivity.
Notice that light loss slot 12 is always located in the outer peripheral surface of bending direction, therefore in all diameter sensor natural shrinking shapes
When state, the luminous flux in photocon 11 is the smallest.Increase with degrees of expansion is stretched, 11 bending degree of photocon becomes
Small, then luminous flux is increased monotonically, therefore luminous flux and stretching degrees of expansion are proportional.
The driving input of sensor is current value, and luminous quantity is proportional with driving current；The output of sensor is
Current value, in the case where supply voltage is constant, output electric current and the luminous flux that surface receives are proportional, it can
All diameter sensors are measured by measurement output size of current and stretch degrees of expansion, and output electric current is directly proportional to degrees of expansion is stretched
Relationship ensure that measurement is accurate.The size of electric current is exported by real-time monitoring, it can long-term real time on-line monitoring Zhou Jing to reach
The effect of variation.
Current type input and output design can carry out zero initialization to output electric current by adjusting driving current, disappear
Remove the individual difference of sensor, moreover it is possible to which output electric current is converted by simple circuit by voltage value.Convenient for the zero of sensor
Initialization, calibration, calibration, measurement cost are low.
13 shape of covering is that congruous continuity is flat everywhere, and overall structure is fine and close, and elasticity, toughness, tension etc. are mechanical special
Property it is approximate with conventional fiber consistent so that the sensor for optical fiber under the premise of no sacrifice service life, reach
The purpose that luminous flux is significantly monotonically changed with bending is arrived.
The sensor processing method is simple, and process costs are cheap, improves production efficiency, low manufacture cost.Week is filled up
The blank of diameter sensor, makes it possible long periods of wear, so that carrying out long-term real time on-line monitoring to object being measured becomes
It may.
Two bonding pads are interconnected, so that measured object is surround and is close to by elastic base 23, and make photocon 11
In the side of 23 periphery of elastic base.When measured object struts elastic base 23, light emission component 21 and light-receiving component 22
Distance increase；And when measured object and the retraction of elastic base 23, the distance of light emission component 21 and light-receiving component 22 reduces.From
And realize and the stretching, extension of photocon 11 is driven by the variation of measured object diameter or is shunk, it is finally reached the function of detection measured object diameter
Can, increase the functionality and applicability of sensor, plays effect convenient to use.
