Thermoacoustic Emitter
Broadband air-coupled ultrasound source
Product details
The Thermoacoustic Emitter (TAE) is a unique, air-coupled ultrasound source for ultrasonic excitation over a broad frequency range. The transducer generates a Dirac-shaped, spatially focused, ultrasound pulse via a fast electronic discharge. The Thermoacoustic Emitter operates as a broadband ultrasound source without moving parts and hence is an excellent match with XARION's Optical Microphone. Applications for the transducer include non-contact ultrasound evaluation (NDE) of materials, and acoustic spectroscopy.
