発明の名称 (英語) INSTALLATION STRENGTH MEASUREMENT DEVICE
発明の概要(英語) According to a conventional method for determining a resonance frequency, vibration of an implant or the like is caused using light, and the state of the vibration is subjected to frequency analysis. However, the method requires the use of a strong light source, and therefore imposes a lot of burden when used. This installation strength measurement device is characterized by comprising: a vibration-causing light generator for irradiating a measurement object with light having varying intensity; a vibration measuring instrument for measuring at least the vibration intensity of the measurement object between the vibration frequency and vibration intensity of the measurement object; and a controller for obtaining information pertaining to the installation strength of the measurement object by causing the vibration-causing light generator to irradiate the measurement object with the light at a plurality of irradiation cycles, obtaining the amplitude intensity from the vibration measuring instrument at each irradiation cycle, and selecting a vibration frequency providing the highest vibration intensity. The installation strength measurement device is usable without any restriction and imposes least burden on a user, because the installation strength measurement device determines the resonance frequency of a fixed object using weak light.
