Abstract
An acousto-optic imaging method in which light waves and unfocused acoustic waves having various directions of propagation m are emitted in a medium, by spatially modulating the amplitude of the ultrasonic transducers of an array of transducers according to several periodic spatial amplitude modulations j, and the resulting optical signal S(t) is captured. For each direction of propagation m, the signals S(t) are spatially demodulated in order to determine a signal S(t) used to reconstruct the image of the medium.
