Offering speed, flexibility and accuracy at a reasonable cost, galvanometer-based optical scanners or ‘galvos’ are the ideal positioning solution for a myriad of scientific, imaging, industrial and ...

The mirror galvanometer is one of several instruments used for measuring small amounts of electrical current. Its use in psychological research led to greater understanding of the physiological ...

Abstract: IN THE ordinary use of a galvanometer, its response to a small voltage in a closed circuit is almost always the point of interest; its action can only be completely understood if the ...

A galvanometer is an instrument that detects an electric current by producing a rotary deflection of ‘a pointer’ with respect to the electric current flowing via a coil in a magnetic field. These were ...

IN 19311 1 described the use of a differential photoelectric cell connected to a ‘secondary’ galvanometer for amplifying the movements of a ‘primary’ one. The only suitable cell available then was a ...
