Non-spherical particle backscattering coefficients as low as 5 {\\times} 10-8 m-1.sr-1 have been measured and the particle depolarization ratio detection limit is 0.6 %. This achievement is based on a well-designed detector with laser-specified optical components (polarizers, dichroic beamsplitters) summarized in a synthetic detector transfer matrix.
