Scanning beam displays use a light source to project video image directly on the retina of the eye, producing a bright, high‐resolution picture. These displays can be used in either occluded or see‐through mode in any applications where a conventional displays; e.g. cathode ray tube CRT would presently be used. Depending on the luminance required by the applications, different types of light sources can be used in the system. For occluded applications light‐emitting diodes LEDs can be used and for see‐through applications usually a laser is used. This paper analyzes the effects of the scanned beam on the retina compared to eye safety standards in place. Analysis for displays designed for military and consumer markets are presented.
