Military utilities
VRDs have been investigated for military use as an alternative display system for Helmet Mounted Displays. However no VRD-based system has yet reached operational use and current military HMD development now appears focused on other technologies such as holographic waveguide optics.
Medical utilities
A system similar to car repair procedures can be used by doctors for complex operations. While a surgeon is operating, he or she can keep track of vital patient data, such as blood pressure or heart rate, on a VRD. For procedures such as the placement of a catheter stent, overlaid images prepared from previously obtained magnetic resonance imaging or computed tomography scans assist in surgical navigation.
Cameras
In the mass-market of digital cameras, scanned-beam displays provide better image quality at lower power and cost than liquid-crystal-on-silicon and organic LED displays.
Scanned-beam technology is capable of displaying images, the data channel through a digital-to-analog converter controlling the light source to paint a picture on a blank canvas in a display. When an image is captured, the light source is turned on, and the data channel looks at the reflections from the object through an analog-to-digital converter connected to a photodiode. The light source, beam optics, and scanner are essentially the same in both applications.
