| Abstract | Most studies of soot relied on sequential interrogation of the flame using narrower laser beams to provide spatial resolution. Typical fractional noise levels of 0.005 in the transmission measurements have been achieved over the fairly lengthy scans that are required to map a flame. This resulted in signal dynamic ranges of 50:1 for the typical attenuation level found in these flames. In addition, the soot concentration gradients in these flames are often very high and flame movements of spatial reading errors of as little as 50 microns can be significant, yet most work has been performed with laser beams with a spatial resolution of 1 mm. With these problems in mind we have set out to design and build an optical system that would provide significantly more accurate line-of-sight attenuation 2-D maps of soot in laminar flames. Our target is a dynamic range of 250:1 (noise level of 0.001) and radial spatial resoluton of 50 um. |
