One hundred years ago Michelson discovered circular polarization in reflection from beetles.
Today a novel Mueller-matrix ellipsometry setup allows unprecedented detailed …

Since one hundred years it is known that some scarab beetles reflect elliptically and near-
circular polarized light as demonstrated by Michelson for the beetle Chrysina resplendens …

The optical properties of several scarab beetles have been previously studied but few
attempts have been made to compare beetles in the same genus. To determine whether …

The light reflected from the metallic-shiny regions of the cuticle of certain beetles belonging
to the Scarabaeoidea is known since 1911 to be left-handed circularly polarized. Only …

The cuticle of the beetle Chrysina chrysargyrea reflects left-handed polarized light in the
broad spectral range from 340 to 1000 nm. Interference oscillations in the experimental …

We discuss the use of Mueller matrices for characterizing the reflecting properties of beetles,
including matching patterns of significant elements to specific cuticular architectures. In the …

The scarab beetle Chrysina gloriosa is green with gold-colored stripes along its elytras. The
properties of light reflected on these areas are investigated using Mueller-matrix …

The light reflected from scarab beetles illuminated with unpolarized white light is analyzed
ellipsometrically and displayed as the sum of an elliptically polarized spectrum I_p and an …

Beetles of the scarab family are known to reflect circularly polarized light from incident
unpolarized light. They are unusual in that there are many animals that use polarized light in …
