摘要：A laser beam intensity modulation system (100) has a variable delay circuit (122)that is used to control the relative delay in the delivery of a video signal (116) between
two cascaded AOM's (110, 112). This delay circuit is controlled by a delay controller (124)that monitors the intensity modulation of the laser beam (11) to provide feedbackcontrol. This system (100) maximises the rise and fall times of the beam (11) to generateprecise beam modulation required for high speed imagesetters.
