<p>The invention concerns acoustic imaging systems. It consists in producing delays required for the reception signals of each of the sensors (201) of such a system using a set (203) of cells (207) with current memory. Said cells are posted and read by means of two offset registers (204, 205) wherein circulates a single bit per register. The space between the bits delays the signal introduced in the set, to form channels. The system enables the use of very compact acoustic cameras or ultrasonograph probes.</p> |
