International audienceThe interplanetary dust cloud is visible through its scattered light (the zodiacal light) at visible wavelengths. Brightness observations lead to equilibrium temperature and albedo of the particles and their variation as a function of the heliocentric distance. The light scattered by this optically thin medium is linearly polarized with negative values of the degree of linear polarization, PQ, in the backscattering region. We will review the zodiacal light photopolarimetric observations from the whole line–of-sight integrated values to the local values retrieved by inversion. Whenever available, the local PQ variation as a function of the phase angle presents a phase curve with a small negative branch and large positiv...
