| Abstract: | A novel technique of phase-disturbed plate has been proPOSed, which is used to suppress the interference speckles caused by interference among the elements of array-type line focus systems. Using microwave to modulate the phases of lacer beamlets passing through the elements of array, the phase relationship among the wavelets may change rapidly with time.After a thermal smoothing time T, which is less than dynamics resPOnse time th of the targetmaterials, the interference speckles on the target can be smoothed on time. |
