ABSTRACT:
A deformable structure is subjected to a plurality of reduced pressures, causing a bulge in the surface of the deformable structure above a separation in the deformable structure. The cross sectional area of the bulge is measured for each reduced pressure in a plane parallel to the surface of the deformable structure. When the cross sectional area of the bulge does not increase with a reduction in the pressure, the cross sectional area of the bulge approximates the area of the separation. The depth of the separation is calculated using the change in cross sectional area of the bulge per change in pressure.
