A data compression device comprises a pulse generator (1) for generating a chirped laser pulse (300), a spatially dispersive element (306) for generating a plurality of spatially distributed outputs from the input chimed laser pulse, a modulator (400) to modulate digital data onto each output and an inverted spatially dispersive element (307) to recombine the data modulated outputs. A method of data compression comprises generating a chirped laser pulse (300), inputting the pulse to a spatially dispersive element (306), generating a plurality of spatially distributed outputs from the input pulse; modulating digital data onto the distributed outputs; and recombining the data modulated outputs in an inverted spatially dispersive element (307). |
