Collimators

Collimated light is a bundle of light rays traveling parallel to one another which implies the light will not disperse with distance. Collimating Displays have been in existence for at least 30 years. Some credit Singer-Link with developing the first collimating display for training a pilot with a more realistic visual display system that included a television monitor being reflected off a beam splitter and onto a concave spherical mirror, the positioning of which provided the observer with light rays that were essentially collimated.

The value of collimated light in simulation and gaming is that it provides the viewer with the most accurate and realistic depiction of the simulation activity, unlike flat panel trainers.
