✦ Synopsis

Two alternative procedures to measure the temperature distribution in an axisymmetric hot water jet using the principle of speckle photography are reported. The two methods differ in the position of the speckle generator with respect to the jet and light source. They produce comparable results, but the uncertainties associated with them are different owing to dissimilar fringe visibilities.

Speckle velocimetry with forward scattering has been applied to measure and visualize the two-dimensional velocity field in an internal gravity wave. The wave was produced by towing a cylinder in vertical direction, normal to its axis, through stratified salt water. Neutrally buoyant tracer particle
