Abstract
An optical interrogator for illuminating an object comprising a laser, a splitter, an optical polarizing element, and an optical recombiner. The laser is configured to generate a laser pulse, which the splitter splits into first, second, third, fourth, fifth, and sixth laser segments such that each of the laser segments are separated by a time delay on the order of nanoseconds between each laser segment. The optical polarizing element is positioned so as to respectively polarize the first, second, third, fourth, fifth, and sixth laser segments with a 0° linear polarization, a 45° linear polarization, a 90° linear polarization, a 135° linear polarization, a right-handed, circular polarization (RHCP), and a left-handed, circular polarization (LHCP). The optical recombiner combines the polarized laser segments into a train of co-aligned pulses for illuminating the object.
