| Abstract: | ![]()
We present a method of synchronizing a shutter for a video camera that allows an instantaneous slow-motion visualization of fast repetitive processes with a time scaling factor of up to 1,000,000 or more. The method uses standard, unmodified CCIR or EIA video equipment, including video cassette recorders for low-cost recording. A number of examples showing spatio-temporal dynamics in nonlinear optical systems is shown, including magneto-optical beam-splitting, drifting hexagons and phase synchronization of coupled solid-state lasers. |
