Measurement of Displacement of Optical Fiber Using Light Intersection Method
نویسندگان
چکیده
Connecting method of optical fibers by V-shaped groove is used in various fields. And in this met,hod, i t is important to estimate distortion of a fiber, because a distortion of the optical fiber influences a connection characteristics. We developed measurement technique of a n optical fiber distortion using Light Intersection Method and optimized incidence angle of the laser beam on a Sample and developed the algorithm to measure with high accuracy. By using our method, the repeatability of the measurement of optical fiber distortion is within 1.2pm as 30.

An optical fiber sensing method based on a reflective grating panel is demonstrated for lateral displacement measurement. The reflective panel is a homemade grating with a periodic variation of its refractive index, which is used to modulate the reflected light intensity. The system structure and operation principle are illustrated in detail. The intensity calculation and simulation of the opti...
متن کاملFabrication and Characterization of the Fiber Optical Taper for a Surface Plasmon Resonance Sensor
For a fiber optical surface plasmon resonance (SPR) sensor a short part of its cladding should be removed to coat a thin layer of a metal. Usually this is problematic when an optical fiber with small core diameter is used. In this paper, a new method using µliter droplet of the HF acid for short fiber optical taper fabrication is reported. Using this method in a multi-mode optical fiber w...
