ACOUSTIC WAVE TRANSDUCER DEVICE |
摘要 |
An acoustic wave transceiver device comprising a sheet of material which responds electrically to acoustic waves and a signal processor which processes the voltage signal produced by the sheet is disclosed. The sheet has an irregular shape which depends on a width function. The sheet produces a voltage signal representing the convolution of the acoustic signal information in a received wave and the width function. The signal processor deconvolves the voltage signal using said width function which is stored in its memory. A method of selecting the width function (and therefor the shape) based on the Fourier transform of a mathematical relation with orthogonal properties is also disclosed.
