Ultrasonic microscope |
摘要 |
An ultrasonic microscope displays an ultrasonic wave image of a sample relatively and two-dimensionally scanned with respect to an ultrasonic wave beam transmitted from and focused by a transducer including a piezoelectric element and an acoustic lens. The F number of the acoustic lens is variably changeable while the scan in one direction of the two-dimensional scan is substituted by a time axis scan of the received echo.
