This optical fiber sensors are being widely used alternative to conventional sensors in various applications because of small size, relatively light weight, high sensitivity and wide bandwidth. Also it has immunity to electromagnetic interferences, because of their dielectric, glass, or plastic nature, they are usually small and light, and they allow remote electric signal opto-electronic conversion and processing. In various uses of optical fiber, intensity modulation type sensor due to misalignment has practical usefulness because it can be realized in ease with low cost and simple structure. To overcome low sensitivity problem in intensity modulation type optical fiber sensor, inclined-cut optical fiber is considered here. Based on optical geometry, the inclined-cut optical fiber sensor is designed and fabricated. The experiments are carried out to evaluate sensor performance. The optical fiber sensor developed in this paper has sufficient precisions and therefore it is available to measure the vibration without contact.
