Abstract: Two orthogonally disposed acousto-optic deflectors produce a rectangular matrix of light spots in the usual way. A series of mirrors arranged to form a staircase convert the rectangular matrix to a close approximation of a linear array. The number of resolvable spots in the linear array is equal to the product of the capacities of the individual deflectors. In turn, by adding a third acousto-optic deflector the linear array can be expanded to form an enlarged rectangular matrix. In principle, this process can be repeated as often as desired, thereby to realize relatively simple light deflection systems characterized by advantageous capacity-speed products.
