| Research Abstract |
Multi-channel optical wave microphone was constructed with a laser, optical fibers, collimator lens, optical divider, and optical switch. We developed 4 channel optical wave microphone system in this line of research. The characteristics of the multi-channel optical wave microphone system was evaluated and the calibration for the optical outputs among 4 channels was carried out.
Distribution of discharge sound which was emitted from surface discharge device was able to be measured with this system. The distribution strongly depended on the frequency of the high voltage source that applies to the electrode of the discharge device. It was found that discharge sound could be detected rather far position from the device.
