PURPOSE:To allow the optional design of the thickness and the length of a cable and to eliminate the effect of external noise by applying an optical fiber cable to the signal transmission cable connected to an ultrasonic probe to transmit signals in the form of light. CONSTITUTION:Electric pulses provided by a pulse generator 4 are converted into light pulses by a electrooptical converter 5, then the converted signals are transmitted to an ultrasonic probe 3 through an optical fiber cable 6. The light pulses are converted into electric pulses by a photoelectric converter 7, then the electric pulses are applied to an ultrasonic vibrator 8. Ultrasonic wave is emitted from the ultrasonic vibrator 8. The ultrasonic wave reflected on a test piece is converted into an electric signal by the ultrasonic vibrator 8, then the electric signal is transmitted to a picture indicator 12 through a electrooptical converter 9, the optical fiber cable 6, a photoelectric converter 10 and a detector 11. |
