Abstract
An ultrasonic testing system for testing a test object that includes at least one transmitting unit and at least one receiver unit. In an embodiment, the transmitting unit generates a spark gap which generates an ultrasonic vibration either on the surface of, or within, the test object. In particular embodiment, the at least one receiver unit optically measures the vibration of the surface of the test object. Embodiments of the invention also relate to a transmitting means and to a receiving system for an ultrasonic testing system and to a method for operating an ultrasonic testing system.
Claims4
An ultrasonic testing system for testing a test object comprising:
- at least one transmitting unit and a multitude of receiver units, wherein each receiver unit optically measures the vibration of a surface of the test object;
- an illumination laser is provided, the light of which illuminates the surface in a measurement area, wherein one of the multitude of receiver units receives light which is incident in that receiver unit from the measurement area, wherein the measurement area is associated with a respective receiver unit, so that the one of the multitude of receiver units receives light which is incident in the receiver unit from the measurement area;
- a light guiding system which radiates the light of the laser in a first position of the light guiding system into a first measurement area and in a second position of the light guiding system into a second measurement area, wherein the light guiding system splits the light of the laser and radiates it into the first measurement area and into the second measurement area;
- further comprising a multitude of transmitting units, wherein each transmitting unit generates a spark gap, and wherein the spark gap generates an ultrasonic vibration on the surface of, or within, the test object.
