This device, which Thomson dubbed the mirror galvanometer, could detect signals one thousand times fainter than other receivers. Thanks to Thomson's invention, the weak currents through the ...

Traditionally, point-scanning confocal microscopes have used galvanometric (galvo) mirrors to generate high-contrast images of a variety of samples. While highly effective for routine imaging ...

William Thomson's marine mirror galvanometer, made by Siemens and Halske, Berlin, Germany, 1850-1900.

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 ...
