研究目的
Investigating the feasibility of synchronizing multiple independently controlled MEMS mirrors for applications in smart mobility and autonomous driving.
研究成果
The study successfully demonstrated the feasibility of synchronizing two independently controlled MEMS mirrors using a novel master-slave synchronization system architecture. The synchronization was achieved by adapting the slave MEMS Mirror frequency to match the master's, controlled automatically by the slave’s PLL. However, the design requires further enhancements to address robustness issues for practical applications.
研究不足
The current design lacks robustness against shocks and frequency changes of the master’s MEMS Mirror, indicating a need for further improvements to ensure applicability in operational modes.
1：Experimental Design and Method Selection:
The study involved designing a master-slave synchronization system architecture for MEMS mirrors. The methodology included the use of FPGAs for rapid prototyping and evaluation.
2：Sample Selection and Data Sources:
Two separate MEMS Drivers were used, one as a master and the other as a slave, to test the synchronization.
3：List of Experimental Equipment and Materials:
MEMS Mirrors, MEMS Driver ASICs, FPGAs, oscilloscope for measuring Position signals.
4：Experimental Procedures and Operational Workflow:
The test was divided into initializing the devices independently in asynchronous mode and then activating the synchronous mode on the slave device to observe synchronization.
5：Data Analysis Methods:
The synchronization process was evaluated by measuring internal states of the slave’s MEMS Driver and the Position signals of both master and slave with an oscilloscope.
