Abstract
Provided is a mechanically-coupled tuning fork-scanning probe vibrating system, the system including: a tuning fork vibrating due to an AC voltage applied thereto; a scanning probe attached to a side of the tuning fork and vibrating due to the tuning fork; and a contact member contacting a side surface of the scanning probe and adjusting a position of a contact point at which the contact member contacts with the scanning probe, to vary a natural frequency of a combination body in which the tuning fork and the scanning probe are combined with each other. A natural frequency of the mechanically-coupled tuning fork-scanning probe vibrating system is closer to a natural frequency of the tuning fork itself by using a dynamic vibration control method using a contact member so that a energy loss of the mechanically-coupled tuning fork-scanning probe vibrating system can be minimized, a quality factor of the mechanically-coupled tuning fork-scanning probe vibrating system can be maximized, the quality factor can be actively controlled regardless of an environment of a specimen to be detected and both a specimen in air and a specimen in a liquid medium with high viscosity can be detected with high resolution.
