Abstract
The invention comprises a device (10) for testing a test object (40), comprising an excitation system (13) for generating broadband ultrasound pulses (12′) in the test object, a detection system (20) for detecting ultrasound waves (21), which are generated through the broadband ultrasound pulses (12′) in the test object (40) and emitted by the test object (40). The device (10) comprises a processing unit (30) for processing the detected ultrasound waves (21), while the excitation system (13) being one of a thermoacoustic emitter or a pulsed laser and the detection system (20) is a broadband detection system. The excitation system (13) comprises a modulator (11) for modulating the broadband ultrasound pulses (12′). Furthermore, the invention comprises a method for testing a test object.
