Packages and methods for storage and dispensing of materials, e. Reduced levels of speckle in the images generated by the device are obtained by forming a B-scan from a plurality of A-scans, wherein each resolution cell of the B-scan is generated through compounding of a subset of the A-scans and wherein at least some of the subset of A-scans are separated by at least half the diameter of a speckle cell both tangent to and orthogonal to the B-scan at that cell. The virtual object may appear to be just below the surface of the physical object. The probe-specific information may be retrieved by the processor from the probe memory via the communications interface.
