Technical Description
The invention is a novel combinational mask-based grating methodology and system to simultaneously co-generate ultrasonic waves using laser excitation. It employs the nonlinear wave-mixing of these generated waves via unique slit arrangements to actively detect early-stage material damage and perform non-contact microstructural characterization.
