10 January 1977 Galvanometer Compensation To Extend Its Frequency Range
Author Affiliations +
Without compensation, moving-coil mirror galvanometers make acceptable repetitive saw-tooth light beam scanners at frequencies up to 10% of their natural frequencies. With the electronic compensation described here, that range can be extended to 30% of their natural frequency.
