摘要:
A system and methods for broad area visual obscuration around a platform. In one embodiment the system comprises a source of visible light, shaping optics and projecting optics. The system projects a light beam onto an illumination area in a sweeping pattern to repetitively illuminate all portions of the illumination area, such that a stationary observer within the illumination area receives repeating pulses of the light at a power, intensity, frequency and duration sufficient to visually impair the observer so as to substantially prevent the observer from discerning the platform between pulses. The light pulses are capable of temporarily blinding human eyes but incapable of causing permanent vision loss.
