Abstract
Vibration is useful information for various applications including vibrotactile reproduction. However, conventional contact-type vibration sensors sometimes obstruct the original motion, and noncontact-type vibration sensors cannot track a dynamic object like a ping-pong ball in a game. In this research, we propose a non-contact vibration sensing system for dynamic objects, using high-speed optical axis control and laser Doppler vibrometer. In our system, low-frequency large motion of the target is tracked by 1000-fps visual feedback, and high-frequency minute vibration is measured by the Doppler shift of a coaxial laser. Then, the prototype of this system realized non-contact vibration measurement with tracking the object.
