摘要

In this work, we develop a microelectromechanical digital-to-analog converter (MEM-DAC) device which serves as a reference mirror with precise nanoscale step motion for a white-light interferometry system. The proposed mechanism converts a 4-bit digital signal to a mechanical out-of-plane displacement that is proportional to the analog value represented by the 4-bit binary code. A fabrication process which can realize a relatively large movable mirror without etching holes is proposed. Measured results are also presented.
