Microvision Laser Monocle: Technician Retina-Vision

Microvision's Nomad Expert Technician System shines laser light right onto your retina, providing images and diagrams that seem to float in the air in front of you.

Surgeons could look down on a patient, and see a projection of the patient's anatomy in place; mechanics are now using it to superimpose diagrams and instructions right on their visual field as they work on engines.

(From Laser vision offers new insights)

Here are the steps:

  1. Light projected to scanning mirror
  2. Pupil expander enlarges the image
  3. Lens focuses the image
  4. Image reflected onto the retina.

And how early were science fiction writers thinking about projecting images directly on the retina? See retinal projection from Frederik Pohl's classic 1952 novel The Space Merchants.
