摘　　要：空间集成传感器比起离散定位传感器更适合于最优控制体系。报道了将此概念应用到振荡传感的情况。束流动力学被应用到集成传感器的设计上,其主要目的是显著地消除或减小高次模的信号幅度。这一设计可以用到没有使用外部信号处理技术,特别是经常应用于工程的钳位-钳位束的振荡传感。Spatially integrating sensor may be more suitable than discrete localized sensors for optimal control architectures. The application of this concept to vibration sensing was described. The fundamental theory for beam dynamics will be used in the design of the integrating sensor, the main goal eliminating or significantly decreasing signal amplitude of the higher modes. This design can be utilized in vibration sensing without the use of extraneous signal processing techniques, especially for clamped-clamped beams, which commonly appear in engineering application.
