|Abstract:|| During the 1950s and 60s, the United States conducted 200+ above ground tests that were captured on 8000+ films in the Nevada desert validating and refining the evolutionary nuclear weapon designs as part of the Cold War strategy. Methods of computerized image analysis of digital streak films from the General Radio slit camera were developed. The methods were implemented to analyze 10 nuclear test films: 2 early fireball films for yield calculations, and 8 streak films for light intensity as a function of time curves. These films are taken from test shots of three operations: Upshot-Knothole, Buster-Jangle, and Tumbler-Snapper. Yield calculations are conducted using Taylor’s shockwave model and the results are compared against data in Eilers’ report. The analysis produced the first-ever light intensity curves on an absolute time scale which capture the entirety of both nuclear thermal pulses for the detonations in the Nevada desert. Additionally, the results identify a phenomenon present in the light intensity curve, both before t1max and around tmin, caused by the wavelengths emitted in the infrared (WEI) phenomenon.
