FlameMaster inspex

The FlameMaster inspex imaging systems apply flame emission spectroscopy to combustion processes. The flame emission (chemiluminescence) of flame radicals like OH*, CH*, C2* is used to e.g. visualize the reaction zone or to monitor flame stoichiometry via emission ratios of such radicals. 2-color pyrometry (blackbody radiation) is used to measure temperature fields in sooty flames.

Flame emission imaging is a line-of-sight (integrating) diagnostic method like absorption. 2D flame species imaging is carried out with a set of filters mounted in front of the camera lens or 1D using an imaging spectrograph for correlated multi-species detection. Line-of-sight images of axisymmetric flames are transformed into 2D radial flame profiles applying Abel inversion. Temporal flame analysis (flame flicker) is measured using statistical information from a time series of flame images. High speed imaging is applied for flame propagation and extinction measurements. FlameMaster inspex systems can be upgraded for laser imaging in flames by adding a laser.
