More Information
Summary:An ultrasonic microscope comprises an acoustic lens, a supporting rod for supporting a sample, a supporting plate for supporting the lens and a drive mechanism for two-dimensionally shifting the lens supporting plate, thereby setting a scanning region, and driving the lens supporting plate to scan the sample to obtain an ultrasonic image thereof. The drive mechanism includes magnetic coils and permanent magnets for shifting the supporting plate by generating a magnetic field, a first power source for producing an electric current for designating the scanning region, a second power source for producing an electric current for scanning, and an adder for adding the electric currents from the first and second power sources and delivering the resulting current to the magnetic coils.
