Spatial-mapping of Flame Radical Emission Using A Spectroscopic Multicolor Imaging-system

In English

Författare

Summary, in English

An intensified multi-colour digital imaging system allowing simultaneous monitoring of light from an object in four wavelength bands was used for flame emission studies. The spatial distribution of the molecular emission from different flame radicals, such as OH, C2, CH, and CN was recorded, also in the presence of a heavy background due to Planck-radiating soot particles. Exposure times down to 8-mu-s could be reached allowing studies of turbulent flames. The imaging spectroscopic recordings were supported by simultaneous point monitoring of the full emission spectrum. A technique for imaging flow measurements using a spectroscopic gas correlation technique is proposed.
