DEVICE FOR GENERATING TEMPORALLY OFFSET , SPATIALLY MODULATED ILLUMINATION REGIONS
A device is provided for generating temporally offset , spa tially modulated illumination regions (22 , 22 ') having peri odic modulation patterns that are phase - shifted with respect to one another . The device has two pulsed laser sources (121 , 122) that are triggerable in a manner temporally offset with respect to one another and that generate two laser beams pulsed in a temporally offset man
