Dual-probe laser interferometer for structural health monitoring (L)

摘要

In this note we present the development of a dual-probe laser interferometer that uses the filtering properties of a polarized beamsplitter to enable two independent (uncoupled) detection probes. The robustness of this system is demonstrated by making broadband, noncontact, high fidelity measurements of Lamb waves in an aluminum plate. (c) 2006 Acoustical Society of America.
