ABSTRACT:
In a method and system to provide high intensity photic stimulation to disable target subjects, a high intensity light source is activated by trigger signals to produce light flashes in commanded patterns of duration and frequency. A user views a field illuminated through a shutter viewer such as shutter goggles. The goggles are gated to a light blocking state in response to trigger pulses. The light blocking state has a wider time width than the light flashes from the light source produced in response to the trigger pulses to avoid the need for close synchronization. The target subjects are exposed to the high intensity light flashes while the light flashes are blocked from the view of users. Due to a low duty cycle, the users' view through the shutter goggles is unaffected by the intermittent opacity of the shutter goggles.
