Abstract
A new camera, that incorporates a high-intensity broad-band flashlamp, has been installed in the CP-121 and CP-140 aircraft. The camera will be used for photographing ships on a 24-hour basis. There is concern about the effect of the bright flash on the visual capabilities of personnel on board the ships being photographed. To assess the potentialy hazard, a review of the literature on the effect of exposure to a bright flash of light on vision, and preliminary calculations of the potential hazard were carried out. On the basis of this preliminary evaluation, there would appear to be no danger of permanent retinal damage following exposure to the flash. A temporary reduction in visual sensitivity is likely especially at very low levels of illumination. A more precise evaluation of the light source and the visual requirements of the tasks being carried out on board ship at night is recommended to substantiate these findings.
