| Abstract: | The application of Laser Induced Fluorescence (LIF) for temperature measurements in water using a Nd : YAG laser is investigated.
A natural convection problem is used to test the applicability of LIF in the temperature range of 20–60°C. The measured temperature
field is compared with numerical results and the influences of shadowgraph effects on the measured temperature field are investigated.
An accuracy of 1.7°C is attained if shadowgraph effects can be neglected. This only holds if correction for photobleaching
and variation of laser power output is applied.
