Compensating Laser Sheet Images of Optically Dense Sprays
Paper in proceedings, 1999

In this paper we present a method for compensating laser attenuation in optically dense sprays, in particular for use in combustion engine research. Images of the fuel sprays are produced by planar laser imaging, where Mie scattered light from a cross section of the spray is imaged onto a CCD camera. The compensation scheme is based on the Beer-Lambert law, which is used here to sum up the loss of light along the path of the laser light in the image, and to compensate iteratively, pixel by pixel, for this loss.
