Abstract
An arrangement for optically creating a full width scanning array from a plurality of small scanning or writing arrays. The small arrays are disposed in alternating staggered relation in two parallel rows on a substrate with the array viewing fields overlapping to prevent discontinuity. The substrate bearing the arrays is placed in optical relation with an array of fiber optic lenses which transmit an image line to or from the arrays. A biprism array composed of plural prisms, one for each smaller array, is located between the substrate bearing the arrays and the lens array. To destagger the separated scanning arrays and produce a single uninterrupted full width scanning array, alternate ones of the prisms in the biprism array are reversed.
