for air-coupled ultrasonic NDE applications", IEEE Trans.
It can match the two or more transducers, pulsers
, receivers, and control electronics systems on a multiple-transducer microscope or large numbers of microscopes in multiple geographic locations.
ICCD-MAX features a built-in pulser
and a custom f/1.2 catadioptric lens.
In addition, changing the excitation signal, upload to pulser
memory and collection of new signals would take time.
This behavior may arise from the uncertainty due to attaching and detaching the pulser
in each measurement.
"This system needs a more powerful pulser
, however, on the order of 1,000 V vs.
A 140-kHz PZT sensor (Dunegan S14013) was used as a receiver with a preamplifier (NF 9913A) or as a transmitter with a 150V, 0.6-[micro]s rise time pulser
. A more practical series used piezoelectric sensors on both ends.
Unless otherwise stated, the rod face attached to the pulser
1), indicating that these are probably frequencies from the pulser
or resonance in the sensor (neither being truly broadband).
