| 摘要 |
The invention relates to a method for determining the spatial concentration of the various components of a mixture, in particular of a gas mixture in a combustion chamber, of a motor for example; a laser beam is hereby directed into the combustion chamber; the laser beam brings the particles of the mixture to radiate, whereas this light of the particles is passed backward through a masked lens and is imaged on a display as a radiating surface and the radial intensity distribution is recorded by an array photodetector, whereas the spatial concentration of individual components of the particle mixture may be measured from the radial intensity distribution.
