- Bucha effect
The Bucha effect is a
seizure -inducing effect of light flashing at 1 Hz to 20 Hz. These seizures are similar to those caused byepilepsy , but are not restricted to people with histories of epilepsy.It is named after a Dr. Bucha who identified the phenomenon in the 1950s when called upon to investigate a series of similar and unexplained
helicopter crashes. Those pilots who had survived reported sudden onset of dizziness and confusion, causing them to lose control of their aircraft. Dr. Bucha found thathelicopter rotor blades, when turning at certain speeds, could cause flashes of sunlight at frequencies coinciding with the electrical frequencies of the central nervous system (brainwaves), inducing symptoms similar to epilepticseizure s, includingdisorientation , nausea, etc.The Bucha effect has been considered as a principle for various forms of
non-lethal weapon .This is related but not the same as
