1. A method of measuring multiple surfaces of an object, the method comprising: using an imaging system to acquire a plurality of two-dimensional (2D) images of the object at a corresponding plurality of scan positions; extracting multiple surfaces of the object from the plurality of 2D images, wherein each of the multiple surfaces represents a distinct physical layer of the object; selecting a plurality of cross-sectional profiles, wherein each of the cross-sectional profiles represents a different one of the extracted multiple surfaces of the object; correcting at least one of the plurality of cross-sectional profiles based on a known characteristic of the object, thereby providing a corrected plurality of cross-sectional profiles; calculating parameters of the object based on at least one of the corrected plurality of cross-sectional profiles; and simultaneously displaying the corrected plurality of cross-sectional profiles using a single x-y plot; and displaying the calculated parameters.
