Abstract
In a light scanning recording or displaying system, a synchronizing light beam is separated from a signal light beam used for recording images or display utilizing the difference in wavelength of the two light beams. The synchronizing light beam and the signal light beam are produced by different light sources of different wavelength and made to advance in the same direction to be reflected and deflected by a light scanning means such as a rotating mirror together in the same direction. After both the light beams are deflected by the light scanning means, the two beams are divided by use of a prism, a holographic plate or a dichroic mirror.
