Abstract
A countermeasure device for the in-band frequency agile laser threat posed to the eyes of operator(s) comprises a rotating shutter operating at a predetermined speed and with alternating clear and nearly opaque sectors. The shutter is designed to spin in front of the operator's field of vision at a rate sufficient to avid a flickering image. The device significantly increases operator protection from an initial laser pulse over existing devices while allowing sufficient ambient light to reach the retina for clear vision. This device will eliminate dazzling which interferes with operator's ability to pinpoint the location of the laser source for neutralization. The device also eliminates the occurrence of damage to both eyes simultaneously.
