The bhangmeter is a non-imaging radiometer developed at Los Alamos in 1948 to detect and measure atmospheric nuclear detonations by analyzing the characteristic double-flash signature of visible light emitted during nuclear explosions. The device became standard equipment on US reconnaissance satellites and KC-135 aircraft, later incorporated into GPS satellites since 1980 for nuclear treaty verification.
