FlameMaster

Laser Imaging for Flame Composition and Temperature Measurements

LaVision’s multifunctional FlameMaster laser imaging system upgraded with an imaging spectrograph measures simultaneously all major species concentration together with flame temperature along a line focus (1D). The line focus of the laser beam probing a flame segment is imaged onto the entrance slit of the spectrograph, which spectrally separates the Raman signals of the different flame species. An intensified camera serves as a sensitive multi-channel detector for all Raman lines and the attenuated Rayleigh signal. Scanning the line focus over the flame generates 2D or even 3D views of the flame composition.

Features
  • 1D gas composition monitoring incl. temperature profile
  • efficient background reduction using polarization rotation
  • data analysis based on calibration measurements
  • line scanning for 2D or even 3D distributions
Key Applications
  • flame composition monitoring (e. g. air/fuel ratio imaging)
  • gas mixing
  • validation of computational models
