Abstract
An acoustic detector which includes at least one emitter unit with a solid tapered profile spike (C) associated with an element (X) for exciting the spike so as to propagate ultrasound waves in an antisymmetrical propagation mode in the spike. The device also emits waves into a surrounding gas. At least one receive unit includes a tapered profile solid spike associated with the detector for receiving the ultrasound waves.
Claims19
An acoustic detector device characterized in that it includes at least one emitter unit including a solid tapered profile spike (C) associated with means (X) for exciting said spike to propagate ultrasound waves in an antisymmetrical propagation mode in said spike and to emit said waves into a surrounding gas and at least one receive unit including a tapered profile solid spike associated with detector means for receiving said ultrasound waves.
