A beamforming system based on the acousto-optic effect
Publication: Research - peer-review › Article in proceedings – Annual report year: 2012
Beamforming techniques are usually based on microphone arrays. The present work uses a beam of light as a sensor element, and describes a beamforming system that locates sound sources based
on the acousto-optic effect, this is, the interaction between sound and light. The use of light as a sensing element makes this method immune to spatial aliasing. This feature is illustrated by means of
simulation and experimental results. For ease of comparison, the study is supplemented with results obtained with a line array of microphones
