Abstract
Laser-based ultrasonic (LBU) systems and methods for measuring at least one material property of a ceramic cellular ceramic body during thermal processing are disclosed. The method includes subjecting the ceramic cellular ceramic body to a temperature cycle within an interior of an oven. For a plurality of temperatures within the temperature cycle, the cellular ceramic body is irradiated with a modulated laser beam to generate acoustic waves in the cellular ceramic body over a plurality of acoustic paths. The method also includes sequentially irradiating the cellular ceramic body using a detection laser beam so that the acoustic waves are detected. The method also includes calculating from the detected acoustic waves at least one material property of the ceramic cellular body as a function of temperature.
