| Research Abstract |
In this project, a very small size mass-spring system was constructed and a vibration experiment was conducted to get the characteristics of the system. The spring had 300 μm in diameter and 1 mm in length. The wire of the spring was 20 μm in diameter. The present mass-spring system was so small that conventional measurement techniques could not be adopted, and we proposed a high-speed digital camera and microscope for the measurement system. The dynamic characteristics of this small vibration system could be obtained successfully. Further, we tried to give some amount of damping to this system by means of the optical radiation pressure produced by a LASER, but its effect could not be obtained in our experiment.交付決定（金額単位：円）直接経費 間接経費 合 計
