摘要： An ultrasonic microscope comprises an acoustic lens for emitting an ultrasonic beam, a movable shaft for supporting a sample, and a drive circuit for moving the movable shaft and thus the sample relative to the acoustic lens in a z-direction. Two signals for eliminating x-direction and y-direction inclinations of the sample relative to the acoustic lens are supplied to the drive circuit in synchronism with an x-direction drive signal and a y-direction drive signal, so that the sample is moved in the z-direction and scanned with the ultrasonic beam in an x-y direction while the sample inclination sample to the acoustic lens is being eliminated.

摘要： An ultrasonic microscope includes a container for containing a liquid nitrogen, and an acoustic lens housed in the container to emit an ultrasonic beam onto the view face of a sample. A sleeve is located above the container, which has a gas-tight chamber therein communicated with the container and a sample inserting opening formed in the periphery thereof. The sample inserting opening is selectively closed and opened by a gate valve. A sample rod is provided with a sample on its lower end, and may be freely movable up and down in the gas-tight chamber to a position where the sample in the container is scanned and to another position adjacent to the sample inserting opening where the sample is exchanged with a new one.

摘要： An ultrasonic microscope includes a housing for containing a cryogenic liquid. A sample support mechanism is secured to a frame inside the housing, and an acoustic lens located in the housing in the cryogenic liquid applies an ultrasonic beam to the sample supported by the support mechanism. A voice coil device suported by the frame operates to move the sample support mechanism in response to a drive current, and to fix a distance between the acoustic lens and the sample. A control arrangement associated with the voice coil device generates an EMF in response to movement of the support mechanism, and supplies a current caused by the EMF to the drive circuit wherein movement of the support mechanism is controlled by the current to maintain the sample at a desired position with respect to the acoustic lens.
