The different grating section of multiple reflection wavelengths is write on fibre, beneficial to realizing array measurement.
The refractive index of periodic variation fibre core, passes through on a certain region of general commercial optical fiber (length about 2-10mm)
Bragg diffraction effect in optical fiber makes the light of specific wavelength be subject to strong reflection.Specific screen periods and effective refractive index
Only there is strong reflex to a part of light wave of smaller bandwidth, and the light wave reflection effect to its all band is very faint.
After being passed through broadband light wave, the reflected return incidence end of light of specific wavelength, is imported in detector by optical splitter, identifies this
The wavelength of part reflected light and corresponding intensity, by identifying the corresponding wavelength of light wave of reflected energy maximum, can obtain phase
The measurement physical quantity answered.
Current imitative Whisker Sensor is realized based on electromotive strain method and Laser Measuring displacement method mostly.Due to these measurements
Element and flexible member can not effectively realize miniaturization, and resolution ratio is difficult to be improved, and structure is too fat to move, so being difficult to realize multiple spot array
Measurement.More it is essential that robot generally requires to work in extreme circumstances, such as nuclear reactor, the outer space, high-temperature pipe
Deng strong-electromagnetic field and big temperature fluctuation will all bring huge interference to electrical measuring method.Traditional electrical measuring method these cannot overcome
The defects of will limit measuring method using electricity as signal vehicle.
