+ Renderings calculated by <a
+ href="man/man1/htrdr-combustion.1.html">htrdr-combustion</a> of a laminar
+ flame seen from above and illuminated by a laser sheet. The images display
+ radiation that is emitted by the laser, scattered and transmitted by the
+ combustion medium. The laser sheet is horizontal, and intersects the medium
+ at various heights. One can see the difference in the scattered signal
+ between the left and right parts of the image; since the laser propagates
+ from the left to the right, it is progressively attenuated while traveling
+ the medium. The intensity of radiation subject to scattering therefore
+ decreases. In addition to these "trapping" effect these images provide some
+ insight about the scattering cross-section of the medium as a function of
+ height. Scattering properties of soot gradually increase from the injection
+ position to a height of approximately 35 mm. A steep decrease follows:
+ the image for a height of 40 mm is very similar to the image obtained at
+ 10 mm.

- This animation (left) simulates a scanning of a combustion medium by the
- laser sheet that emits from the left part of the medium, and propagates to
- the right. Each frame is computed by <a
- href=man/man1/htrdr-combustion.1.html>htrdr-combustion</a> for a different
- position of the laser sheet, that subsequently intersects with different
- zones of the medium. Each image represents what is perceived by the camera
- for this particular position of the laser. The configuration used for this
- simulation is the one retained for the validation of the algorithm (the
- corresponding data set is provided in the <a
- href=htrdr-combustion-spk.html>starter-pack</a> for combustion processes): as
- shown in the representation of the medium data (right), the volumic fraction
- of soot follows an axisymmetric profile, with the main axis centered in the
- cubic chamber, and a maximum at the back.
+ Images rendered with <a
+ href="man/man1/htrdr-combustion.1.html">htrdr-combustion</a> of a flame
+ illuminated by a vertical laser sheet that runs through the central axis of
+ the flame; the camera is looking at the centre of the flame, but its normal
+ is oriented respectively at an angle of 30, 60 and 90 degrees relative to the
+ main direction of the laser sheet. One can see the trapping of
+ radiation by the medium and the decrease of scattering intensity
+ decreases with the angle of observation, otherwise known as the scattering
+ angle.
