Special Issue Information

Dear Colleagues,

MEMS mirror can manipulate light in chips and is a typical kind of optical MEMS actuators. MEMS mirror has been widely used in modulating the phase, amplitude and direction of light, and has gained tremendous commercial applications in the fields of autonomous driving, laser projection, optical communication and intelligent manufacturing. While achieving mass production applications, MEMS mirrors also face significant challenges. For example, in the application of autonomous driving LiDAR, the evaluation criteria, model  and improvement methods for the reliability of MEMS mirrors are not yet comprehensive; In the field of space optical communication, the ability to achieve micro arc level angle measurement and closed-loop control is not yet perfect; In the field of consumer electronics, the complex fabrication process and expensive interface circuits of MEMS mirrors make their cost unable to reach the level of mass use. Therefore, this special issue seeks to showcase research papers, short communications, and review articles that focus on: (1) novel designs, fabrication, control, and modeling of MEMS mirrors Intended to enhance reliability, reduce costs, and improve closed-loop control accuracy; and (2) new applications of MEMS mirrors can be utilized in the fields of aerospace, aviation, industry, agriculture, and consumer electronics.

MEMS-based LiDAR has showcased extensive application potential in the autonomous driving sector, attributed to its cost-effectiveness, compactness, and seamless integration capabilities. However, MEMS LiDAR suffers from a short detection range, due to the small receiving aperture of the MEMS mirror. Our early study attempted to increase the detection range of MEMS LiDAR with a semi-coaxial design. In this paper, we further investigate the synchronization method for large-aperture electromagnetic MEMS mirrors, in which a synchronous motion transfer model of electromagnetic MEMS mirrors is constructed. The results of the simulations and experiments demonstrate that two electromagnetic MEMS mirrors are synchronous with an aperture of 60 π mm2, FoV of 60°, and scanning frequency of 220 Hz. The entire synchronization process of the electromagnetic MEMS mirrors is completed within 10 s, which verifies the feasibility of synchronizing large-aperture electromagnetic MEMS mirrors to increase the detection range of MEMS LiDAR.
