Irradiance Distribution Analysis of Inclined-cut Multi-mode Optical Fiber for Optical Microphone Design

광 마이크로폰 설계를 위한 경사 절단된 멀티모드 광섬유의 조도분포 해석

For designing intensity modulation type optical microphone, the irradiance distribution which can be applied to inclined-cut geometrical configuration is suggested. The model is important in analysis of response characteristics f3r intensity modulation type optical microphone. To overcome low sensitivity problem in intensity modulation type optical microphone, 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.
