Popis:	The reconfiguration time of a holographic beam-shaping device using a liquid crystal spatial light modulator (SLM) has been drastically decreased by five orders of magnitude to reach the microsecond range (~5 µs). The method involves an acousto-optic modulator (AOM) placed in front of the SLM which points the laser beam towards different pre-addressed regions of the liquid crystal plate. Because the addressing signal is not changed, the reconfiguration time is mainly governed by the AOM response time. Moreover, this method allows us to clean up the transient regime by suppressing the bleed effect usually observed in the standard SLM reconfiguration.
