| Abstract(in English) | Sensitivity of a guided-wave optical microphone is theoretically found to be inversely proportional to the square of the diaphragm thickness. Also, according to the theoretical analysis, sensitivity increases with an increase in side length ratio for the side length ratio of less than unity, but the sensitivity shows a plateau for the ratio of more than unity. These dependencies, however, have not been demonstrated experimentally, although they are important in the designing of the optical microphone. In this study, these dependencies were examined experimentally. Based on the sensitivity dependence with respect to the diaphragm dimensions, the optical microphone with a 20 mm×20 mm×0.15 mm diaphragm was fabricated, and then successfully detected a sound wave of 100 dB-SPL. |
