1. A three-dimensional (3D) mechanical probe, comprising:

  • a base,an acoustic window,a hose that has an open, connection end, a closed end, and a central portion between the open and closed ends, anda plug head,whereinthe acoustic window is connected to the base,a sealed space is provided between the acoustic window and the base,the base is connected to a connector,the open, connection end of the hose is connected to the connector,the connector comprises a channel passing through the connector,the central portion of the hose is in communication with the sealed space through the channel,the plug head is connected to and seals the closed end of the hose,the sealed space and the hose are filled with a coupling liquid,wherein;

    the central portion of the hose has a cross-sectional inner circumference, and, in a natural, uncompressed state, a natural, non-circular, inner cross-section taken perpendicular to a lengthwise-extending, central axis of the central portion;

    in a state of minimum operating pressure of the coupling liquid, the central portion is open, permitting flow of the liquid from the sealed space into the central portion;

    in a state of maximum operating pressure of the coupling liquid, the central portion retains an expanded, non-circular, inner cross-section;

    the cross-sectional inner circumference of the central portion remains constant while the shape and cross-sectional area of the central portion vary from the state of minimum operating pressure to the state of maximum operating pressure,whereby the volume of the coupling liquid in the central portion increases as the temperature of the coupling liquid increases and decreases as the temperature of the coupling liquid decreases.
