| 摘要 |
The present invention relates to a three-axis optical acceleration sensor for a seismometer and, more specifically, to a three-axis optical acceleration sensor for a seismometer, capable of carrying out accurate earthquake simulation by measuring all three-axis directions using one sensor, ensuring a long-term usage by applying optical fiber to have good durability, and carrying out more accurate measurement by not being affected by the surrounding environment. The present invention comprises a cube-shaped case; a mass body responding to vibration by being placed inside the case; a Y-axis guide allowing the mass body to vibrate left and right; an X-axis guide allowing the mass body to vibrate back and forth; a Z-axis guide allowing the mass body to vibrate up and down; and a senor unit installed on the mass body. |
