Abstract

It is well known that various artifacts interfere with circular dichroism (CD) measurement using the polarization modulation technique. In this report, we propose a simple analysis method for eliminating the artifacts derived from the residual birefringence of a phase modulator. We consider the origin of the artifacts and find that those in CD can be distinguished by analyzing signals as a function of the retardation of the phase modulator using a Mueller matrix method. We experimentally obtain pure CD from a sample with CD and linear dichroism by applying retardation domain analysis.
