微光机电系统(MOEMS)加速度计具有精度高、抗电磁干扰、环境适应性好、可靠性高及易小型化的特点,是未来惯性仪表的重要发展方向。根据光学检测原理对现有微光机电系统加速度计进行了分类:基于直接光强调制、基于光的波动性、基于光与物质相互作用的微光机电系统加速度计;基于测量原理和典型案例,分析了这3类微光机电系统加速度计的优缺点和适用场景;结合微光机电系统加速度计的研究进展,提出了其未来发展的趋势和重点方向。

A micro-opto-electro-mechanical system(MOEMS)accelerometer features high precision,electromagnetic interference resistance,good adaptability to the environment,high reliability,and easy miniaturization,which is the major development trend of inertial instruments.According to the optical measurement principle,this paper divides MOEMS accelerometers into three categories,which are based on the direct intensity modulation(IM),the undulatory property of light,and the light–matter interaction separately.Following a brief introduction to the measurement principles and typical cases,we systematically analyze the merits and demerits of the three accelerometers,as well as their potential application scenarios.Given the research progress in MOEMS accelerometers,we also present their development tendencies.
