Abstract
The acoustic analog to the single-pixel imager found in the optical and THz imaging literature is presented. Here, the single-pixel detector is replaced with a single omnidirectional acoustic receiver and combined with a series of masks that allow for multiple orthogonal measurements. Acoustic source localization is performed based on the theory of compressive sensing which allows for the resolution of N acoustic sources using M measurements where M << N. A theoretical model for the acoustic single pixel imager is presented and compared to finite element models (FEM) simulated in COMSOL and experimental data taken in an air acoustic 2D waveguide. It is shown that the acoustic single pixel imager is capable of localizing multiple targets using only a single omnidirectional acoustic receiver. [Work supported by the Office of Naval Research.]
