This paper proposes an approach for acoustic field imaging using simultaneous multi-view digital holography based on three-color digital off-axis holography. Considering spatio-chromatic multiplexing and the recording with a monochrome sensor, the numerical processing of time-sequences of holograms yields both the amplitude and phase of the acoustic field along three different directions of observation. Experimental results with an emitter at 40kHz establish the proof-of concept of the proposed multi-view imaging for acoustic fields. Tomography imaging of the acoustic field is provided with multiple recordings when rotation the transducer.
