Abstract
Devices for detecting plate bending, or flexural, waves include at least two mechanical resonators positioned on a plate in a specified configuration. Each mechanical resonator has an associated oscillation amplitude detector, such as a laser vibrometer, configured to detect resonant oscillation of the mechanical resonator in response to an incident flexural wave. A ratio of frequency-dependent oscillation data for each mechanical oscillator is compared to a calibration curve to determine the angle of incidence of the flexural wave.
