摘要：Embodiments of the present invention are directed to pulsed polarimeters for conducting remote, non-perturbative diagnostic measurements of inducing fields of a medium demonstrating induced optical activity. In one aspect, a pulse polarimeter includes a light source emitting a polarized light pulse having sufficiently narrow spatial extent at a prescribed wavelength and a light gathering optical system including a light gathering optic having an optic axis directed toward the medium and positioned to collect and collimate a predetermined solid angle of an emission from the medium into a collimated emission beam, while preserving the polarization state of the emission. The pulse polarimeter includes a directional coupler that makes coincident the propagation direction of the polarized light pulse with the optic axis and a polarization detection system for measuring the intensity and determining the polarization state of the collimated emission beam continuously in time as the polarized light pulse transits the medium.
