DEVICE FOR THE ACQUISITION OF COORDINATES OF AN ACOUSTIC SOURCE APPLIED TO A PLATE |
摘要 |
The invention discloses a device for the aquisition of coordinates (x, y) of an acoustic source (S) applied to a plate (P) in variable positions. The plate comprises an assembly of acoustic receivers (Rx<->, Rx<+>, Ry<->, Ry<+>). The device comprises means for determining the times of arrival of the acoustic waves which propragate in the plate from the source, and means for establishing coordinate data as a function of said times. According to the invention, the source operates in an asynchronous mode and the conversion means are appropriate to establish the coordinate data as a function of the difference between the propagation times of the acoustic waves towards the various receivers. |
