摘要
This paper investigates phase synchronization and concordant resonance of micro-mirror arrays and describes in detail a proposed design for a segmented micro-mirror with elastic linkages. The device replaces a conventional large area mirror, thus increasing the working frequency and allowing micro-mirror arrays to induce smaller vibration amplitude. The torsional micro-mirror array is fabricated using three conventional masks based on silicon bulk-micromachining technology. Experimental results of the prototype sample show that the phase difference among the mirror segments of the mirror array is below 1/15 cycle. 2001 Elsevier Science B.V. All rights reserved.
