Abstract
A laser beam comprising at least two different wavelength components is directed to be incident upon an acousto-optical modulator which is excited with acoustical waves having selected acoustic frequency to optical wavelength relationships such that collinear modulated light beams are transmitted. The system is further arranged such that the modulator functions optically in a video bandpass filter mode, to diffract the collinear color components at maximum intensity and substantially free from mutual interference. Systems are also disclosed in which the thus modulated beam is scanned and display energy is directed for maximum light output efficiency.
