摘要： A scanning probe microscope having a probe for scanning a sample, a piezoelectric unit finely movable in the X, Y and Z directions, and a probe control unit for controlling a fine movement amount of the piezoelectric unit in the Z direction in accordance with a detected interaction between the sample and the probe. A driving unit applies a continuously changing voltage to the piezoelectric unit to drive the piezoelectric unit in one of an X and Y direction to scan along a scan line, a displacement detection unit detects the displacement of the piezoelectric unit along the scan line, and a matching detection unit outputs a coincidence detection signal when the detected displacement of the piezoelectric unit along the scan line coincides with target displacement values corresponding to desired measurement points. A surface data acquiring unit acquires sample surface data based on the Z-directional fine movement amount of the piezoelectric unit each time the matching detection unit outputs a coincidence detection signal.

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.
