| 中文摘要 | We design a dual axis rotary mirror based on microelectromechanical system technology used for the endoscopic optical coherence tomography (OCT) application. With the inherent advantages of the micromachined device such as small size, low consumption and high reliability, it allows the miniaturization of conventional bulky OCT probe. The dimension of the micro-mirror is 140um×270um. Through use of finite element method, the simulation results show that the scanning mirror is capable of high frequency out-of-plane rotation in two mutually independent axes. The natural frequencies of the first two modes, corresponding to tip and tilt modes, are 65.74 KHz and 65.75 KHz respectively. The MEMS scanning mirror is electrostatically actuated with the supply voltage ranging from 30v to 40v. Via 2-axis scanning, a three-dimensional image of biological tissue can be acquired when the MEMS mirror is integrated with the OCT probe system. The entire MEMS scanner can be fabricated using the proposed surface-micromachining process, capable of mass production. |
