Paper Abstract

The use of GaAsP light emitting diodes as pulsed light sources for high-speed photography is discussed. Two applications are des-cribed: single-shot photography with pulses ca. 1 p,s long, and stroboscopic visualization of ultrasound with 50 ns flashes. The luminous efficiency and current capacity of the LEDs was considerably enhanced by cooling them to 77 K in liquid nitrogen.
