Abstract:

The dipole shutter was investigated as a possible eye protective device for the deleterious effects of high-intensity flashes. Both theory and engineering design have been explored to ascertain if the principle could be developed into a usable device. A transparency with minute electrodes etched on its surface has been found to provide sufficient electrostatic field strength for various alignments, and it is believed that this cell will be ophthalmically acceptable. Heretofore, herapathite solution has been utilized to provide the dynamic medium for change in optical density of transmission. Other submicron metallic whiskers have been analyzed to find if the antenna effect could be enhanced. No such enhancement was noted, and possibly some other mechanism is responsible for the varying effect. The dipole shutter may still prove to be an effective eye protective device because of its several desirable features however, the range of dynamic change in optical density apparently will not be as great as predicted by theory.
