Image of submillimeter ice crystal formation at 6 km altitude. The image is taken with special measurement system installed at the wing of an airplane. Due to the high velocity of the plane, capturing the ice crystals without motion blur requires a very short camera shutter or light pulse. CAVILUX is used in the setup as illumination because of its ability to create very short light pulses.
