What Are Digital Micromirror Devices?
Definition and Functionality
Digital Micromirror Devices are micro-electromechanical systems (MEMS) that consist of an array of microscopic mirrors. Each mirror is mounted on a hinge and can tilt to reflect light in specific directions. By individually controlling each mirror, DMDs modulate light with incredible precision, making them an integral part of systems like digital light processing (DLP) projectors, medical imaging tools, and 3D printers.
Core Technology Behind DMDs
Each mirror in a DMD operates independently, tilting on an axis at speeds of up to thousands of times per second. These rapid adjustments allow DMDs to create detailed and dynamic light patterns that form images or guide other processes, such as laser cutting or optical communication.
Brief History of DMD Development
DMD technology was pioneered in the late 1980s by Texas Instruments, a company that remains a leader in this field. Initially designed for DLP projectors, DMDs have since evolved into multi-purpose tools with applications across medical, industrial, and entertainment sectors. Digital Micromirror Devices (DMDs)
