1. An optical beam switching system for transmitting an optical beam from a source to any one of a group of optical receptors comprising:

  • a focusing lens for focusing an optical beam and directing the optical beam along a selected path;

    a first movable mirror mounted in the selected path;

    a plurality of second movable mirrors and a plurality of optical receptors;

    a control for moving the first movable mirror to direct the optical beam to any selected second mirror and for moving the selected movable mirror to direct the optical beam to a selected optical receptor for transmission of the optical beam from the focusing lens to the selected optical receptor; and

    radiation emitters disposed adjacent each movable mirror to provide a feedback signal to the control for adjusting the position of the movable mirrors to minimize transmission loss of the optical beam to the receptor.
