ABSTRACT:
An image display method and apparatus in which a laser beam is modulated to vary in intensity in response to electric or electromagnetic signals received and is traversed along a photosensitive film carried on a rotating carriage by means of a stepwise driven, friction damped carriage synchronized with respect to the drum rotation, the drum being mounted on magnetic bearings for rotation about a preferably vertical axis. Optionally the modulated beam may be split and a part of the split beam used as a feedback signal controlling the modulation for compensating for the intensity of the beam emerging from the laser.
