Abstract:
A thickness gauge for a laminated structure having multiple layers, the thickness gauge comprising:a transducer for emitting signals into the laminated structure to create multiple signal echoes corresponding to the multiple layers of the laminated structure;the transducer further including means for receiving the multiple signal echoes and for generating electrical transducer signals proportional to the signal echoes received by the transducer;a pulser for sending pulses to the transducer to generate the emitted signals;a sampler for sampling the electrical transducer signals from the transducer; anda processor for analyzing the electrical transducer signals sampled by the sampler to detect individual ones of the received multiple signal echoes and to determine a thickness of each of the multiple layers for which individual signal echoes were received;wherein the processor includes means for subjecting the sampled electrical transducer signals to a deconvolution analysis to distinguish the sampled signals.
