The shape of the vibratory modes can be complex, unexpected and strongly dependent on the frequency. It is often not possible to anticipate it. DHM measures vibration maps without pre-defining any measuring points or grids, allowing characterization without preconceived assumptions of their specific shapes.
Stroboscopic acquisition allows measuring of course simple period of excitation signals but also to measure response to transients, bursts, impulses, or frequency chirps. With a maximum of 200 MHz bandwidth, up to 8196 FFT bins, vibration maps can be measured and analyzed very efficiently and accurately in both time- and frequency-domains.
Mega-pixels resolved vibration mode shapes combined with sample geometries often give rise to aesthetic vibration maps, measured with interferometric resolution to obtain vibration amplitudes as small as picometers.
Large sensors and multi-elements devices may have lateral dimensions much larger than the objective field of view, whereas cross talks between multiple elements require vibration mode shape analysis over their full surface. Used in conjunction with a motorized stage, DHM measures and stitches measurements to provide vibration maps with tens or even hundreds of million data points.
