Article Citation :Jeong-Hwan Hwang ,Kwang Myung Jeon ,Hong Kook Kim ,Chang-Soo Park , (2016 ) " Resolution-Improved Optical Beamformer With A Multiple Line Array Sensor Structure For The Direction Detection Of Low Frequency Acoustic Wave " , International Journal of Electrical, Electronics and Data Communication (IJEEDC) , pp. 25-27, Volume-4,Issue-4

Abstract : To find the origin of acoustic signal, an array type of sensors is necessary, but this array structure accompanies spatial aliasing problem by the finite and discrete number of sensors. This problem can be overcome by using acousto-optic beam forming. For low frequency (< 1 kHz) application, conventional one-dimensional beam forming needs a long beam path. In this paper, two-dimensional beam forming using a multiple line array structure is proposed to improve direction resolution in low frequency range. Its resolution performance is compared through simulation with that of one-dimensional beam forming. Keywords- Two-dimensional beam forming, Acousto-optic sensing,
