Abstract

The optical dispersion of the deflection angle in a laser color TV system using acoustooptic deflection is overcome by using prisms to magnify the smaller deflection angles associated with the blue and green primary images. By using two prisms in cascade, the magnification can be made invariant with deflection angle, and convergence of the three primary images achieved across the entire TV raster. A full color TV projection system is described which uses acoustooptic intensity modulation and horizontal scanning.
