He thought the best response was to devise a device that could read faint signals. The galvanometer, first invented in 1802, was a means of detecting electric current. It consisted of a needle ...

Galvanometer optical scanners also called Galvos or Galvo scanners are motorized mirror mounts and systems used for laser-beam steering or scanning applications. They are ideal for moving small laser ...

"What got you into astrophysics?" It's a question I'm often asked at outreach events, and I answer by pointing to my early ...

It looks as though the machine has been built, at least in a test configuration. A galvanometer aims the death ray using mirrors, and with the low power and lossy mirrors the mosquitos can only be ...

In 1904 John Ambrose Fleming wrote Guglielmo Marconi: "I have been receiving signals on an aerial with nothing but a mirror galvanometer and my device." The device was the original thermionic ...

Unlike other instruments of the day, a mirror galvanometer could clearly show minute current variations by translating tiny movements of the mirror into large movements of the light reflected off ...

with an image-sweep optical system using galvanometer mirrors. It took five years from the planning stage to develop a highly ...

But even with the galvanometer running off the scale, Beria was totally unimpressed. "Is that all?" he wanted to know. He then asked to approach the reactor. When Kurchatov told him that was too ...

The two arms which complete the circuit at the surface are connected with a telephone which takes the place of the customary galvanometer. The theory of this very sensitive and accurate instrument ...
