Temperatur- und Phasenverlauf über der Brennerplatte
A laser beam generates scattered light in the measurement volume. That light is collected by a lens system, spectrally filtered by an iodine cell and finally recorded by an EMCCD or photomultiplier.
A laser beam is reflected through an iodine cell by a sheet of glass and generates there fluorescence (yellow linie). The absorption lines of iodine can be used to cut the scattering of glas walls out of the measurement signal. Therewith the investigation of technical flows is practicable.
