A laser scanned visual display system was evaluated with respect to recent research data and permissible exposure limits. Wide angle laser scanned visual displays can be considered in the following three ways. (1) Instantaneously, the illuminated area can be considered as a finite point, which, if continuously observed, will appear to pulsate at the frame rate. (2) The display can be considered as an extended source, which is pulsating asyncronously at the framing rate. (3) The display can be considered as a continuously illuminated extended source with an average irradiance. Repetitive pulse exposure conditions are implied by the first two considerations, while the third implies a continuous exposure condition. The most stringent restriction on the illuminance of the display screen results when the display is considered as a continuously illuminated extended source. The permissible irradiance on the screen for a 2-hour exposure is 9.2 mw/cm2. The average irradiance (26 Âµw/cm2) of proposed laser scanned displays is well within acceptable limits based upon current permissible exposures.
