Micromachined directional microphones (sound source localization sensor) mimicking an auditory organ of Ormia Ochracea have been intensively studied based on center-supported, marginally free 1-D or 2-D diaphragm structures. Based on an exact mathematical formulation, a Gaussian weight function on the diaphragm is shown to be inevitable in the transduction of 1st and 2nd moments. An analysis was performed...
Micromachined directional microphones (sound source localization sensor) mimicking an auditory organ of Ormia ochracea have been intensively studied based on center-supported, marginally free 1-D or 2-D diaphragm structures. This paper first describes an exact mathematical theory of sound source localization based on the partial differential equation (PDE) formulation of the problem and the weighted...
In this paper, we propose a novel vibrometric imaging technique for two-dimensional and real-time vibration measurement. Our system consists of two major components: 1) projector of moving stripes to encode vibration amplitude and phase into time-varying intensity of light, 2) correlation image sensor (CIS) to select a single frequency component and decode its amplitude and phase distribution in a...
