Methods, systems, and computer-readable media for nondestructively measuring physical properties of a material by observing induced displacements using different focal configurations

A system for measuring a physical characteristic of a material, the system comprising:

• one or more processors;
• and
• memory storing instructions executable by the one or more processors, whereby the system is operable to:
• perform one or more interrogations of a material sample, each interrogation using a push focal configuration;
• take a plurality of measurements of displacement over time of a material sample caused by the one or more interrogations, each measurement using an interrogation focal configuration;
• and
• determine a physical characteristic of the material sample based on the plurality of measurements of displacement over time of the material sample,
• wherein at least one of:
• a tracking focal configuration used for one of the plurality of measurements is different from a tracking focal configuration used for another of the plurality of measurements;
• and
• a plurality of interrogations is performed, wherein a push focal configuration used for one of the plurality of interrogations is different from a push focal configuration used for another of the plurality of interrogations.

A non-transitory computer readable medium storing software instructions that when executed by one or more processors of a system for quantitatively measuring a physical characteristic of a material, cause the system to:

• perform one or more interrogations of a material sample, each interrogation using a push focal configuration;
• take a plurality of measurements of displacement over time of a material sample caused by the one or more interrogations, each measurement using an interrogation focal configuration;
• and
• determine a physical characteristic of the material sample based on the plurality of measurements of displacement over time of the material sample,
• wherein at least one of:
• a tracking focal configuration used for one of the plurality of measurements is different from a tracking focal configuration used for another of the plurality of measurements;
• and
• a plurality of interrogations is performed, wherein a push focal configuration used for one of the plurality of interrogations is different from a push focal configuration used for another of the plurality of interrogations.
