In the last decades, the experimental setup located in Amsterdam,
The Netherlands, has produced a significant number of experimental
scattering matrices as functions of the scattering angle of randomly
oriented small particles. The Dutch setup was closed in 2007. An
improved descendant of the Dutch experimental setup has been recently
constructed at the Instituto de Astrofísica de Andalucía, CSIC, the IAA cosmic dust laboratory.
To provide an incentive for further research and applications all
published Dutch and Spanish experimental data are accessible through
Summary of samples in the Amsterdam-Granada Light Scattering Database.
March 20th, 2013 In this paper we present measurements of the complete scattering matrix as a function of the scattering angle of a sample of (birefringent) calcite particles. Numerical (DDA) calculations are compared with the experimental data. We find that birefringence has little impact on the calculated phase functions but it has a significant effect on the polarization-related elements of the scattering matrix. Moreover, we conclude that the shape of the targets (flakes or irregular rhomboids) has a much stronger effect on the computed scattering matrix elements than birefringence. Read more
