BEYOND PROJECTION, HOW DIGITAL MICROMIRROR DEVICES REVOLUTIONIZE 3D IMAGING AND INDUSTRIAL INSPECTION

Digital Micromirror Devices (DMDs) are made of many small reflective electromechanical surfaces that can be tilted to project light coming from a single or multi-wavelength source onto a specific target area. In some cases, the same technology can also be used to generate point cloud, 3D RGB images by capturing the light that is reflected off the target surface.

One DMD can contain an array of millions of micromirrors. When combined with a high-speed camera and a micromirror-modulating controller, DMDs allow for the inspection of small to large, manufactured parts with very high accuracy, even when the target being imaged is highly reflective.

By projecting a pattern onto the target to be inspected and capturing the distortion of that pattern when the light meets the surface, DMD-based systems can be used to detect manufacturing flaws and measure the dimensions of the target being imaged.

DMD systems find applications in:

• Manufacturing

• Spectroscopy

• Reverse engineering

• Robotic guidance

• and more.
