Innovation from December 1963.
The tiny white button in the lens can detect and amplify, by 100 times, signals carried to it on less than a billionth of a watt of light.
The transistor-like device, a quarter-inch in diameter, would be the heart of a matchbox-size receiver, enabling space systems to pick up light-borne signals beamed from millions of miles away.
Sperry Rand researchers, who developed it, hope to make it still a billion times more sensitive-comparable to seeing, from the moon, the glow of a 400-watt bulb on earth.
