Paper Abstract

A high frequency stroboscope for flash rates up to the 101-1z region will be described. The flashes are generated by light emitting diodes which emit - especially in the pulse mode - high light currents in the visible region. The pulse width of the flashes is controlled automatically in such a way that the mean light. current stays constant for flash rates between 100 Hz up to 1 MHz. The ratio between flash duration and period length is adjustable over a wide range, hereby the height of the light pulses is regulated internally for h.,-lean light current output. Some applications of the stroboscope in Mach-Zehnder-, 'N'Tirau- and Differential-Interferometry and an example for the observation of a desintegrating water-jet will be given.
