It is very important and desirable in laser treatment that the laser beam is irradiated to the target on a body surface keeping with the exact exposure condition throughout the treatment. The authors have devised a new laser exposure system the laser beam of which follows up the movement of the subject. This system is consisted of (1) tracer of a moving target, (2) computer output control unit for tracing signal of the moving target, (3) X-Y controller for operating X-Y table by the tracing signal and X-Y table to drive a laser handpiece to follow the moving target.
