Abstract |
In this paper, direction estimation to sound source using an array of two optical fiber sensors based on time difference of arrival is introduced. The sensor array consists of two Mach-Zehnder interferometers including an acousto-optic sensor for each one. The direction estimations for two cases of direction, one about 1.5 m apart from the center of the array and the other about same length apart from a corner of the array, are performed to gunshot sound signal. Estimation lines appeared in speaker range, respectively, compared with the ideal values in free sound field and anechoic condition.
