Abstract
Active Strobe Imager (ASI) equipped with actuator and strobe flashing is known as convenient visualization tool for an object vibrating with high frequency that human eye cannot follow. In order to obtain quantitative data as well, this paper proposes to utilize in phase action mode by synchronizing both actuator and LED lightening, which makes the target object as if it stops moving. By implementing both force and vision sensors, we can obtain the equation of motion of object between the force and displacement with the mechanical impedance. By solving the inverse problem, we obtain the mechanical impedance numerically.
