ultrasonic transducer การใช้

• Mineralization of the ultrasonic transducers requires maintenance and potential for component failure.
• Most of the commercial ultrasonic transducers today are based on piezoelectricity.
• Ultrasonic transducers showing ~ 20 kHz and ~ 40 kHz stacks.
• Ultrasonic transducers convert AC into ultrasound, as well as the reverse.
• This method works with an ultrasonic transducer scanning the wafer bond.
• The ultrasonic transducer raster-scans the top surface of the sample.
• The generated ultrasonic waves are detected by ultrasonic transducers and then analyzed to produce images.
• It may use microphones, accelerometers, and multifrequency ultrasonic transducers.
• It is used in a number of practical applications such as ultrasonic transducers and piezoelectric resonators.
• Each path consists of an ultrasonic transducer at one end and a sensor at the other.
• Unlike all other ultrasonic techniques, RUS ultrasonic transducers are designed to make dry point contact with the sample.
• "' Capacitive micromachined ultrasonic transducers "'( CMUT ) is a relatively new concept in the field of ultrasonic transducers.
• Backward propagation predictions can be used to analyze the surface vibration patterns of acoustic radiators such as ultrasonic transducers.
• "' Capacitive micromachined ultrasonic transducers "'( CMUT ) is a relatively new concept in the field of ultrasonic transducers.
• It was also known that the precompensation schemes placed an added demand on the frequency response of the ultrasonic transducers.
• The diagrams show the sound fields of an unfocused and a focusing ultrasonic transducer in water, plainly at differing energy levels.
• An ultrasonic transducer is affixed to a stainless steel pan which is filled with a solvent ( frequently water or isopropanol ).
• In the first demonstration of the Photoacoustic Doppler effect, a continuous wave photoacoustic microscopy setup with an ultrasonic transducer as the detector.
• In a similar way to radar and sonar, ultrasonic transducers are used in systems which evaluate targets by interpreting the reflected signals.
• The second term represents the frequency shift in the photoacoustic wave due to the motion of the absorbers observed by the ultrasonic transducer.
