Description

Chiral objects typically exhibit a different extinction for the two circular polarizations of light. Researchers often detect the chirality of objects by measuring this extinction difference employing Circular Dichroism (CD) spectroscopy. In this talk, we present a new spectroscopy technique for detecting the chirality of spherical objects based on measuring the Stokes parameters at any non-forward angle. The chirality measure we introduce effectively eliminates achiral background noise and is independent of both the object's concentration and the optical path length. Furthermore, we demonstrate that the technique is robust and verifiable in-situ by measuring the Stokes vector at two different non-forward angles of choice.
