AI-Generated Summary
A 1946 memorandum proposing the use of spectrographic analysis and rotating-shutter cameras to identify and measure the speed of V-bombs. The author suggests a collaboration between the company Aga and the Swedish National Defence Research Institute to develop the necessary equipment.
This memorandum, dated August 2, 1946, and written by an observer named Zygmunt [illegible] from Saltsjöbaden, addresses the technical challenge of distinguishing V-bombs from meteors using spectrographic methods. The author notes that meteor spectra are highly characteristic, typically defined by calcium lines. The author posits that by utilizing an open camera setup, as suggested in an attached sketch, it is possible to capture the spectra of V-bombs, which would likely differ significantly from those of meteors. Such an analysis could provide critical information regarding the composition of the gases involved. Additionally, the author proposes that if cameras were equipped with rotating shutters, it would be possible to observe regular interruptions in the V-bomb's trail, thereby allowing for the calculation of its speed—a technique already established in astronomical studies of meteors. The author concludes by suggesting that multiple spectrographs of this type should be placed at high altitudes, and that the necessary equipment could be manufactured domestically, specifically mentioning a potential collaboration between the company Aga and the National Defence Research Institute (Försvarets Forskningsanstalt).
