Abstract

A polarimeter includes a multi-wavelength source for generating electromagnetic waves having at least two different wavelengths, means for separating electromagnetic waves, the electromagnetic waves including electromagnetic waves generated by the multi-wavelength source and electromagnetic waves received from a sample contacted by the electromagnetic waves generated by the multi-wavelength source, a fixed waveplate, wherein the fixed waveplate is configured to convert one polarization state to multiple polarization states that allow for calculations of linear and circular polarization components of the electromagnetic waves, a free space coupler, a beam splitter, and more than one detector. The polarimeter may be used in a method for high-speed measurement of linear and circular polarization components of electromagnetic waves.
