The acoustic imager, also referred to as an acoustic camera, is a sound source positioning device based on digital microphone array technology.

Imaging Process

The front-end microphone array collects acoustic signals distributed across the spatial sound field. Mainstream algorithms including beamforming, time delay estimation and acoustic holography are applied to process signals and generate sound source coordinate data. The processed acoustic mapping is then superimposed onto real-time visible light footage captured by the integrated camera to produce fused acoustic-optical images with marked sound source locations.
