Scanner and Moving Heads

Scanner and Moving Heads are the devices for moving light in a room. The scanner is a spotlight whose light beam is deflected by an electromechanically movable mirror. The moving head is a head-moving spotlight that can be swiveled around two axes. In contrast to the scanner, the moving head moves the entire "head" including the light source. Whereas with the scanner the light source is fixed and the mirror or mirror roller moves.
