ABSTRACT:
A laser scanning apparatus having at least one light source which emits a light at selective intensity, a light scanning device to scan the light emitted from the light source, a waveguide bundle which receives the light at one end of the waveguide bundle and the other end of the waveguide bundle is aligned to form a displaying screen, a phosphor coating screen and a set of photo-detector array which can receive the light passing through each bundled waveguide path. A picture is created by the scanned emission of the light at the other end of the waveguide bundle, or by the scanned emission of a set of phosphor struck by the light. An interactive signal transmission is achieved by sending an optical signal into the other end of the waveguide bundle to let the photo-detector receive the optical signal, and by sending an optical signal from the light source to the other end of the waveguide bundle by way of the waveguide path to let an outer photo-detector receive the optical signal at the other end of the waveguide bundle.
