| Abstract: | A pulsed light generator for stroboscopic photography which makes use of LED's has been developed. The maximum light power which may be extracted from a single LED is approximately 1 Watt. The pulse repetition rate ranges up to 1 MHz and the length of the pulses is adjustable between 0.05 and 1  s. The light emitted from the diodes is especially suited for the observation of phase objects by interferometric methods due to its pronounced coherence. Results of the electrical and optical performance of the generator are presented. |
