在美国加州理工学院和罗切斯特大学,研究人员已经开发出一种超灵敏的微传感器加速度计。这种设备使用激光探测运动,尽管设备很小,它仍旧能够极其敏感地探测运动。由于其低质量,它还可以在一个大范围的频段内运行,这意味着它能够探测到发生在几十微秒内的运动,比现在使用的传感器可以探测到快数千倍的运动。加州理工学院的应用物理学教授 At the California Institute of Technology and the University of Rochester, researchers have developed an ultra-sensitive micro-sensor accelerometer. This device uses laser detection motion, and although the device is small, it can still detect motion with extreme sensitivity. Because of its low mass, it also operates over a wide range of frequency bands, which means it can detect movements occurring in dozens of microseconds, thousands of times faster than currently used sensors.
