Abstract: A measuring device and method are disclosed for parameter distribution measurement over the entire surface of sheet-like objects. The parameters of primary interest are thickness and permeability profiles. The device includes a parameter measuring unit a coordinate measuring unit and a synchronization unit to control operation of the parameter measuring unit and the coordinate measuring unit. The coordinate measuring unit determines the measuring device position on two-dimensional surface using image correlation analysis. The measuring device further comprises a platform for its movement in the plane of the sheet-like object.
