Abstract (en)
[origin: WO9903016A1] The electrical (RF) crosstalk in multi-channel laser beam systems using an acousticoptic modulator is minimized. This is done without reducing packing density by arranging the modulator electrodes (44a, .., 44h) in a two dimensional array. The electrodes in each column are staggered relative to the electrodes in adjacent columns. While this introduces a problem of potential gaps between the resulting laser beam spots, this gap is corrected by a beam translation device (50) located in the optical path of certain of the laser beams.
