| Abstract: | Within two appointed areas, the current coming out of the reflective photoelectric switch is direct ratio with the distance between the reflector and the instrument. By using this characteristics, this paper gives out a vibration-detecting system to discuss the extraction of the signal of weakly vibration being out of touch with the vibrator. |
