Abstract
An ultrasonic probing system including: a recurrent electric impulse sender, several transducer devices integral with a common support and connected to said sender; receptor devices connected with said sender, wherein the transducer devices are arranged to include focal areas which together cover an extended area essentially perpendicular to the common support and the connection between the transducer and receptor devices includes means for introducing a variable transfer characteristic; and programming devices controlling said introducing means in order to cause said characteristic to vary as a function of the elapsed time after transmission of each electrical impulse whereby the system operates with an effective focal spot coinciding at each probing instant with the tested area.
