A digital micromirror device (DMD) is an array of individually switchable mirrors that can be used in many advanced optical systems as a rapid spatial light modulator. With a DMD, several implementations of confocal microscopy, hyperspectral imaging, and fluorescence lifetime imaging can be realized. The DMD can also be used as a real-time optical processor for applications such as the programmable array microscope and compressive sensing. Advantages and disadvantages of the DMD for these applications as well as methods to overcome some of the limitations will be discussed in this article. Practical considerations when designing with the DMD and sample optical layouts of a completely DMD-based imaging system and one in which acousto-optic deflectors (AODs) are used in the illumination pathway are also provided.
数字微镜器件（DMD）是一种由可单独切换的微镜组成的阵列，可在许多先进光学系统中用作快速空间光调制器。利用DMD，可以实现共聚焦显微镜、高光谱成像和荧光寿命成像的多种实现方式。DMD还可用作实时光学处理器，用于可编程阵列显微镜和压缩传感等应用。本文将讨论DMD在这些应用中的优缺点以及克服一些限制的方法。还提供了使用DMD进行设计时的实际考虑因素，以及完全基于DMD的成像系统和在照明路径中使用声光偏转器（AOD）的成像系统的样品光学布局。
