Bhangmeters

All satellites used for atmospheric nuclear detonation monitoring incorporate a detection device called a bhangmeter. Bhangmeters detect and record the distinctive double-humped optical signature of an atmospheric nuclear detonation.

The name bhangmeter originated with some of the early skeptics who did not believe such sensing was possible. "Bhang" is a variation of Indian hemp that is smoked for its hallucinogenic impact. Apparently some thought that anyone who believed such an approach feasible must have been smoking hallucinogens.
