摘要
A probe primarily applicable to medical echography for achieving a variable compromise between depth of field and lateral resolution incorporates a main piezoelectric transducer, a plano-convex lens having an elastic diaphragm, an auxiliary transducer for measuring the deflection of the lens and means for controlling the deflection in dependence on a reference value by modifying the pressure exerted on the diaphragm by the fluid contained within the lens.
