Abstract

Two-dimensional images of Mie scattered light from a water aerosol have been recorded by a streak camera with a time resolution of a few picoseconds. The laser pulse, which is 35 ps long, is repeatedly reflected and refocused in the probe volume. On the output phosphor screen of the streak camera, the images of the scattering appear as adjacent, separated pictures on the temporal axis of the streak camera. Because the pictures obtained in this way are separated in time by less than 3 ns, which is much shorter than the typical time scales of the turbulent gas flow, and because they are separated in space by fixed intervals, the resulting images can be used to compose a three-dimensional picture of the aerosol distribution.
