1. An inspection system comprising:
a transducer probe configured to transmit an acoustic wave from a first location on an object;
a target configured to be selectively coupled to a surface of the object and scatter the transmitted acoustic wave from a second location on the object to produce a returning acoustic wave including a plurality of time-series features; and
a control circuit configured to receive information about the returning acoustic wave for simultaneous determination of a plurality of characteristics relating to physical properties of the object based on plurality of time-series features in a calibration mode, wherein the control circuit is configured to generate a system of n equations including n time-series observations and n unknown plurality of characteristics, and wherein the control circuit is configured to simultaneously calculate the n plurality of characteristics using the system of n equations, wherein n is greater than 1,
wherein the inspection system is configured to use the plurality of characteristics for inspecting the object for potential defects in an inspection mode.
