The DSD replaces the analog control board in a conventional
scan head. It provides digital control of two galvanometer
scanners with analog position detection. This symbiosis of
analog and digital technology allows well-proven analog
technology to be equipped for the future due to new, digital
possibilities. Despite its compact size, complex mathematical
problems are solved in real time by effi cient algorithms, which
turns the DSD into a perfect tool for innovative solutions.
