The principles of Fourier transformation are applied to photoacoustic imaging. Advantages are threefold: reduction of the power density at the sample; improvement of signal to noise ratio due to multiplexing advantage; and increase of spatial resolution by additional measurements with masks corresponding to higher overtones. The compatibility of Fourier with other multiplex transform techniques is discussed.
