MUTs transform an electrical signal into an acoustic one, through a mechanical complex movement. Designers make use of several electrical, mechanical and acoustical models, and each of them depends on many physical parameters. Therefore, there is a strong need to compare simulation and in-situ experimental results.
The main vector for this signal transfer is the membrane movement of the MUT. Measurement of its 3D topography time-sequence along the phase of the excitation signal is needed for understanding the energy transfer processes.
Full field measurement enables simultaneous characterization of many MUT membranes. It enables analysis of:
The topography of each membrane is measured over its complete surface with high lateral resolution, enabling:
Lyncée Tec stroboscopic module enables short burst mode excitation, commonly used for medical imaging modes.
The DHM® unique optical configuration enables measurement of the deformation of immersed membranes resulting from both the transmitted wave and the receiving acoustic echo.
