摘要：

We aim to develop a MEMS mirror fabricated by micro-fabrication technology to realize a phase-shift device, which is a key component of a two-dimensional Fourier spectrometer. This MEMS mirror is capable of high-precision movement in the vertical direction parallel to the reference plane. In this study, a vertical electrostatic comb-drive actuator and capacitance sensor were fabricated monolithically on a single chip, and then four of them were mounted around the movable mirror. We fabricated a MEMS mirror that was able to move in the vertical direction while sensing the tilting angle. As a result, it would be feasible to use this vertical comb-drive MEMS mirror with a sensing function for a phase-shift device that was able to control the vertical displacement and the tilting angle of a movable mirror.
