...Christmas Day the worst pea soup fog in three decades descended on London. It was not the fog, however, which brought tears to British eyes and lumps to millions of British throats. Loyal subjects, drawn in sympathy to King George VI as never before, heard His Majesty bravely make a Christmas broadcast, his halting voice strained with emotion. In effect what the King had to tell his people was that the great effort to overcome his speech impediment, an effort which he has made for years and, which carried him through his Coronation without skipping or mispronouncing a single word...
Visible light does not penetrate thick fog, but visible light is only a small segment on the wide spectrum of electro-magnetic radiation. Radiation which is too long in wave length to be seen, called infra-red and embracing wireless waves of all lengths, has the faculty of sliding around obstacles such as fog particles. Therefore an artificial eye which "sees" by infra-red radiation appears to offer the best hope of piercing fog...
Four years ago Commander Paul Humphrey Macneil demonstrated a fog-eye which made use of infra-red radiation in the region of heat waves, naturally emitted by all objects warmer than absolute zero (TIME, May 8, 1933). It turned on warning lights, rang a gong when a fog-shrouded vessel passed another ship. Few months later Master Mariner Flavel M. Williams installed on the Manhattan and Washington a camera which took a picture of an obstacle through fog by infra-red radiation, producing the developed film 30 seconds after exposure (TIME...
Last week the talk among communication engineers was of a new fog-eye which, instead of simply signaling, obtains a picture like the Williams device but does so immediately. Patented by Clarence W. Hansell of Rocky Point, N. Y. and assigned to Radio Corp. of America, the apparatus emits radio waves so short that some of them bounce back from an obstacle to the sending point, where they are focused so as to create a tiny image on a copper sulfate screen.* The picture emerges as a white silhouette on a blue background. If the obstacle is a ship...
